What is the characteristic property of a transverse wave?
- A.
The particles of the medium oscillate parallel to the direction of wave propagation.
- B.
The particles of the medium oscillate perpendicular to the direction of wave propagation.
- C.
The wave transfers energy through compression and rarefaction of the medium.
- D.
The wave travels in a straight line and does not bend around obstacles.
Correct Answer
B. The particles of the medium oscillate perpendicular to the direction of wave propagation.Explanation
In a transverse wave, the particles of the medium oscillate or vibrate in a direction that is perpendicular to the direction of the wave's propagation. This distinctive motion creates crests and troughs in the wave. The crests are the points where the particles are at their maximum displacement from their equilibrium position, while the troughs represent the points where the particles are at their maximum displacement in the opposite direction.Rate this question:

What is the formula for calculating the frequency of a wave?
- A.
Frequency = Wavelength / Amplitude
- B.
Frequency = Period / Amplitude
- C.
Frequency = Velocity * Wavelength
- D.
Frequency = 1 / Period
Correct Answer
D. Frequency = 1 / PeriodExplanation
The frequency (f) of a wave is the number of oscillations or cycles that occur per unit of time. It is inversely related to the period (T), which is the time it takes for one complete cycle to pass a given point.
In other words, to find the frequency, you take the reciprocal of the period. If you know the period of a wave (the time it takes to complete one cycle), you can calculate the frequency by dividing 1 by the period.Rate this question:

Which of the following statements is true about the amplitude of a wave?
- A.
It represents the distance between two consecutive crests or troughs of a wave.
- B.
It determines the number of oscillations per unit of time.
- C.
It is the maximum displacement of a particle in a wave from its equilibrium position.
- D.
It determines the speed at which a wave travels through a medium.
Correct Answer
C. It is the maximum displacement of a particle in a wave from its equilibrium position.Explanation
The amplitude of a wave refers to the maximum displacement or distance that a particle within the medium (such as air, water, or a solid substance) moves from its equilibrium or rest position as the wave passes through. In simpler terms, it measures how far the particles are moved from their normal, undisturbed position by the wave.Rate this question:

- A.
Meters (m)
- B.
Kilograms (kg)
- C.
Watts (W)
- D.
Hertz (Hz)
Correct Answer
D. Hertz (Hz)Explanation
The unit of measurement for frequency is Hertz (Hz). One hertz is equivalent to one cycle or oscillation per second. It is named after the German physicist Heinrich Hertz, who made important contributions to the study of electromagnetic waves. Therefore, when we say a wave has a frequency of 10 Hz, it means it completes 10 cycles or oscillations in one second.Rate this question:

Which of the following characteristics of a wave determines the pitch of a sound wave?
- A.
Amplitude
- B.
Wavelength
- C.
Frequency
- D.
Velocity
Correct Answer
C. FrequencyExplanation
The characteristic of a wave that determines the pitch of a sound wave is Frequency. The pitch of a sound is how high or low it sounds, and this is directly related to the frequency of the sound wave. Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches. Therefore, when discussing the perception of pitch in sound, it is the frequency of the wave that is most relevant.Rate this question:

What is the relationship between frequency and period in a wave?
- A.
They are inversely proportional.
- B.
They are directly proportional.
- C.
There is no relationship between them.
- D.
The relationship depends on the wave medium.
Correct Answer
A. They are inversely proportional.Explanation
The relationship between frequency and period in a wave is inversely proportional, meaning that as the frequency increases, the period decreases, and vice versa. Frequency represents the number of oscillations or cycles a wave completes in a given time, typically measured in hertz (Hz), while the period is the time it takes for one complete cycle to pass a point.Rate this question:

Which type of wave requires a medium to propagate?
- A.
Transverse wave
- B.
Electromagnetic wave
- C.
Longitudinal wave
- D.
Standing wave
Correct Answer
C. Longitudinal waveExplanation
The type of wave that requires a medium to propagate is a Longitudinal wave. Longitudinal waves involve oscillations or vibrations of particles in the same direction as the wave's propagation. They require a material medium, such as air, water, or a solid substance, to transfer energy.In contrast, transverse waves do not necessarily require a medium and can propagate through a vacuum, as seen in electromagnetic waves. Electromagnetic waves consist of oscillating electric and magnetic fields and can travel through space without a material medium.Therefore, the correct answer is: Longitudinal wave.Rate this question:

What is the formula for calculating the velocity of a wave?
- A.
Velocity = Frequency * Wavelength
- B.
Velocity = Amplitude * Period
- C.
Velocity = 1 / Frequency
- D.
Velocity = Amplitude / Period
Correct Answer
A. Velocity = Frequency * WavelengthExplanation
The formula for calculating the velocity (v) of a wave is given by the product of its frequency (f) and wavelength (λ). This formula signifies that the velocity of a wave is determined by how frequently the wave oscillates (frequency) and the distance between consecutive peaks or troughs (wavelength). The relationship highlights that waves with higher frequencies or shorter wavelengths tend to travel at higher velocities, while waves with lower frequencies or longer wavelengths travel at lower velocities.Rate this question:

Which of the following statements is true about a crest in a wave?
- A.
It is the lowest point of a wave.
- B.
It is the highest point of a wave.
- C.
It is the line joining two consecutive troughs of a wave.
- D.
It represents the area of maximum compression in a longitudinal wave.
Correct Answer
B. It is the highest point of a wave.Explanation
A crest in a wave is the highest point or peak of the wave's oscillation. In a periodic wave, such as a transverse wave like a water wave or a light wave, the crest represents the point where the displacement of the medium (like water or air) is at its maximum positive value. This is the point where the particles of the medium are most elevated or displaced from their equilibrium or rest position.Rate this question:

What happens to the frequency of a wave if the wavelength decreases?
- A.
The frequency also decreases.
- B.
The frequency stays the same.
- C.
The frequency increases.
- D.
There is no relationship between wavelength and frequency.
Correct Answer
C. The frequency increases.Explanation
In a wave, frequency and wavelength are inversely proportional. If the wavelength decreases, the frequency increases, and vice versa. This relationship is governed by the wave equation v=f x λ, where v is the velocity of the wave, f is the frequency, and λ is the wavelength. As the wave travels through a medium at a constant speed, a shorter wavelength means more cycles of the wave pass a point in a given time, resulting in a higher frequency.Rate this question:
