    What is the "lowest part" of a transverse wave?

    • Crest

    • Trough

    • Amplitude

    • Frequency

    Correct Answer
    A. Trough
    Explanation
    The "lowest part" of a transverse wave is called the trough. In a transverse wave, the crest represents the highest point while the trough represents the lowest point. The amplitude refers to the maximum displacement of the wave from its equilibrium position, and the frequency refers to the number of complete cycles of the wave that occur in one second.

    What is the distance between the "crest" of one wave and the "crest" of the next?

    • Wavelength

    • Wave

    • Medium

    • Surface wave

    Correct Answer
    A. Wavelength
    Explanation
    The distance between the "crest" of one wave and the "crest" of the next is referred to as the wavelength. Wavelength is a measurement of the distance between two corresponding points on a wave, such as two crests or two troughs. It is commonly represented by the Greek letter lambda (λ) and is an important characteristic of waves, as it determines various properties of the wave, such as its frequency and speed.

    What is the unit of measurement for frequency?

    • Gram

    • Joule

    • Hertz

    • Speed

    Correct Answer
    A. Hertz
    Explanation
    The unit of measurement for frequency is hertz. Hertz is a unit used to measure the number of cycles or oscillations per second in a wave or signal. It is commonly used in physics and engineering to describe the frequency of electromagnetic waves, sound waves, and other periodic phenomena. Gram, joule, and speed are not units of measurement for frequency.

    What is the "highest part" of a transverse wave?

    • Compression

    • Crest

    • Trough

    • Amplitude

    Correct Answer
    A. Crest
    Explanation
    The "highest part" of a transverse wave is referred to as the crest. In a transverse wave, the particles of the medium move perpendicular to the direction of the wave propagation. The crest is the point on the wave where the displacement of the particles is at its maximum, or the highest point above the equilibrium position. It is opposite to the trough, which is the lowest point below the equilibrium position. The amplitude, on the other hand, represents the maximum displacement of the particles from the equilibrium position and is not specifically related to the "highest part" of the wave.

  • 6. 

    What is a number of complete waves that pass a given point in a certain amount of time?

    • Amplitude

    • Compression

    • Rarefaction

    • Frequency

    Correct Answer
    A. Frequency
    Explanation
    Frequency refers to the number of complete waves that pass a given point in a certain amount of time. It is a measure of how many times a wave completes its cycle in a specific time interval. In other words, frequency determines the rate at which the wave oscillates or vibrates. The higher the frequency, the more waves pass through the point in a given time, while a lower frequency means fewer waves passing through.

    What is the part of a longitudinal wave where the particles of the medium are close together?

    • Compression

    • Rarefaction

    • Crest

    • Trough

    Correct Answer
    A. Compression
    Explanation
    In a longitudinal wave, the particles of the medium are close together in the compression region. This is because the compression region is where the particles are pushed closer to each other, resulting in a higher density of particles. This increase in density causes an increase in pressure within the medium. Therefore, compression is the correct answer to the question.

    Rate this question:

  • 8. 

    What is the maximum distance the particles of a medium move away from their rest positions as a wave passes through a medium?

    • Amplitude

    • Compression

    • Crest

    • Trough

    Correct Answer
    A. Amplitude
    Explanation
    The maximum distance that particles of a medium move away from their rest positions as a wave passes through a medium is called the amplitude. The amplitude represents the maximum displacement of the particles from their equilibrium positions and indicates the intensity or strength of the wave. It is a measure of the energy carried by the wave and determines the loudness or brightness of the wave in the case of sound or light waves, respectively.

    What is a wave that that occurs at the surface between  two medium?

    • Surface wave

    • Trough

    • Longitudinal wave

    • Wave

    Correct Answer
    A. Surface wave
    Explanation
    A surface wave is a type of wave that occurs at the surface between two different mediums. It is a wave that travels along the boundary or interface between the two mediums, rather than through them. Surface waves can be seen in various natural phenomena, such as ocean waves, seismic waves, and ripples on the water's surface. They have characteristics of both transverse and longitudinal waves, as they exhibit both vertical and horizontal motion. Surface waves are important in understanding the behavior of waves and their interactions with different mediums.

    Rate this question:

  • 10. 

    What is the part of the longitudinal wave where the particles of a medium are "far" apart?

    • Trough

    • Compression

    • Rarefaction

    • Crest

    Correct Answer
    A. Rarefaction
    Explanation
    In a longitudinal wave, the particles of the medium move back and forth parallel to the direction of wave propagation. During rarefaction, the particles are "far" apart, meaning they are spread out and have a lower density compared to the other parts of the wave. This is the opposite of compression, where the particles are close together and have a higher density. The trough refers to the lowest point of a transverse wave, not a longitudinal wave. The crest is the highest point of a wave, which is also not applicable to the question.

    Rate this question:

  • 11. 

    Which wave moves the medium in a direction "perpendicular" to the direction in which the wave travels?

    • Longitudinal wave

    • Surface wave

    • Transverse wave

    • Mechanical wave

    Correct Answer
    A. Transverse wave
    Explanation
    A transverse wave is the correct answer because it is a type of wave in which the particles of the medium move perpendicular to the direction in which the wave travels. In a transverse wave, the oscillations or vibrations occur at right angles to the direction of energy transfer. This is in contrast to a longitudinal wave, where the particles of the medium move parallel to the direction of the wave. Surface waves and mechanical waves are not specific types of waves, but rather categories that can include both transverse and longitudinal waves.

  • 12. 

    What is a disturbance that transfers energy from place to place?

    • Compression

    • Wave

    • Wavelength

    • Trough

    Correct Answer
    A. Wave
    Explanation
    A wave is a disturbance that transfers energy from one place to another. It is characterized by the oscillation or vibration of particles or fields in a medium. Waves can be mechanical, such as sound waves or water waves, or electromagnetic, such as light waves or radio waves. They can travel through different mediums, including solids, liquids, and gases. Waves can have various properties, including wavelength, frequency, and amplitude. In the context of the given question, a wave is the correct answer as it best describes the phenomenon of energy transfer through disturbances.

    Rate this question:

  • 13. 

    Which wave moves the medium "parallel" to the direction in which the wave travels?

    • Surface wave

    • Transverse wave

    • Mechanical wave

    • Logitudinal wave

    Correct Answer
    A. Logitudinal wave
    Explanation
    A longitudinal wave is a type of wave where the particles of the medium move parallel to the direction in which the wave travels. This means that the particles oscillate back and forth in the same direction as the wave is moving. In contrast, a transverse wave is a type of wave where the particles of the medium move perpendicular to the direction in which the wave travels. Therefore, a longitudinal wave is the correct answer because it is the only type of wave listed that moves the medium parallel to the direction of the wave.

    What is a repeated back-and-forth or up-and-down motion? 

    • Frequency

    • Wave

    • Vibration

    • Compression

    Correct Answer
    A. Vibration
    Explanation
    Vibration refers to a repeated back-and-forth or up-and-down motion. It is a rapid oscillation or movement that occurs around a central position. This can be observed in various objects and systems, such as the movement of a pendulum, the buzzing of a phone, or the shaking of a car on a bumpy road. Vibration is characterized by its frequency, which determines the number of cycles or oscillations that occur per unit of time.

    What is a wave that requires a medium through which to travel?

    • Transverse wave

    • Longitudinal wave

    • Surface wave

    • Mechanical wave

    Correct Answer
    A. Mechanical wave
    Explanation
    A mechanical wave is a wave that requires a medium, such as air, water, or solids, to travel through. This is because mechanical waves transfer energy by causing particles in the medium to vibrate. In contrast, transverse waves and longitudinal waves can both travel through a vacuum, as they do not require a medium. A surface wave, on the other hand, is a combination of both transverse and longitudinal waves and can travel along the surface of a medium. Therefore, the correct answer is mechanical wave.
