About This Quiz

Sound waves are produced whenever a disturbance occurs in the air. Such disturbances are common in everyday life and include sound produced from playing musical instruments.

    The movement of molecules towards each other causes  - ProProfs

    The movement of molecules towards each other causes 

    • Compression

    • Rarefraction

    • Troughs

    • Crests

    Correct Answer
    A. Compression
    Explanation
    The movement of molecules towards each other causes compression. When molecules are compressed, they are pushed closer together, resulting in an increase in density and pressure. This can occur in various contexts, such as in a gas being compressed into a smaller volume or in a sound wave where air molecules are compressed and create areas of higher pressure.

  • 3. 
    The distance between one compression to the other is  - ProProfs

    The distance between one compression to the other is 

    • Amplitude

    • Wavelength

    • Period

    • Displacement

    Correct Answer
    A. Wavelength
    Explanation
    The distance between one compression to the other is referred to as wavelength. Wavelength is a physical property of a wave and is defined as the distance between two consecutive points in a wave that are in phase. In the case of a compression wave, such as sound waves, the distance between two consecutive compressions is the wavelength. This property is important in understanding wave behavior and is commonly used to describe various types of waves, including electromagnetic waves and seismic waves.

    The behaviour of a vibratory particle in sound waves is like  - ProProfs

    The behaviour of a vibratory particle in sound waves is like 

    • The heartbeat

    • A spiral spring

    • A wiper

    • A rotating fan blade

    Correct Answer
    A. A spiral spring
    Explanation
    A spiral spring is a suitable comparison for the behavior of a vibratory particle in sound waves because both exhibit similar characteristics. Just like a spiral spring oscillates back and forth when disturbed, a vibratory particle also moves in a similar manner when subjected to sound waves. The particle vibrates in a periodic motion, with its displacement from its equilibrium position changing over time. This comparison helps to understand the nature of sound waves and how particles interact with them.

    Sound waves do have which of these properties? - ProProfs

    Sound waves do have which of these properties?

    • Reflection

    • Diffraction

    • Rarefraction

    • Refraction

    Correct Answer
    A. Rarefraction
    Explanation
    Sound waves do have the property of rarefaction. Rarefaction refers to the decrease in density of a medium caused by the passage of a sound wave. As a sound wave travels through a medium, it creates areas of high pressure (compression) and low pressure (rarefaction). The rarefaction regions are characterized by a decrease in the density of the medium, which causes the particles in the medium to spread out. This property of sound waves is important in understanding how they propagate and interact with different mediums.

    Which of the following is odd? - ProProfs

    Which of the following is odd?

    • Trumpet

    • Violin

    • Wall clock

    • Radio

    Correct Answer
    A. Radio
    Explanation
    The given options consist of musical instruments and a wall clock. These items are typically associated with producing sound or music. However, a radio is not an instrument and does not produce sound on its own. Instead, it is a device that receives and plays audio signals from various sources. Therefore, the radio is the odd item in this group.

    The fact that sound waves require a material medium for propagation make them - ProProfs

    The fact that sound waves require a material medium for propagation make them

    • Transverse waves

    • Longitudinal waves

    • Electromagnetic waves

    • Mechanical waves

    Correct Answer
    A. Mechanical waves
    Explanation
    Sound waves require a material medium, such as air, water, or solids, for propagation. This is because sound waves are the result of vibrations or disturbances in the particles of the medium. These vibrations travel through the medium in a wave-like manner, causing the particles to oscillate back and forth in the same direction as the wave. Therefore, sound waves are classified as mechanical waves, which are waves that require a material medium to propagate.

    Which of these is not true about sound wave? - ProProfs

    Which of these is not true about sound wave?

    • It require a medium for propagation

    • It can be polarised

    • It is a pressure wave

    • It is a mechanical wave

    Correct Answer
    A. It can be polarised
    Explanation
    Sound waves cannot be polarized. Polarization refers to the alignment of the electric field vector of a wave in a specific direction. Sound waves are mechanical waves that require a medium for propagation, and they are pressure waves that travel through compressions and rarefactions in the medium. However, sound waves do not exhibit polarization because they do not have an electric field component.

    Which of these cannot be polarised? - ProProfs

    Which of these cannot be polarised?

    • Light wave

    • Radio wave

    • X-ray

    • Sound wave

    Correct Answer
    A. Sound wave
    Explanation
    Sound waves cannot be polarized because polarization refers to the alignment of the electric field vector of a wave in a specific direction. Sound waves are mechanical waves that require a medium, such as air or water, to propagate. They do not have an electric field component, and therefore cannot be polarized.

    The fact that sound cannot travel through a far distance reveals that  - ProProfs

    The fact that sound cannot travel through a far distance reveals that 

    • It has long wavelength

    • It has short wavelength

    • It has long amplitude 

    • It has long amplitude

    Correct Answer
    A. It has long wavelength
    Explanation
    Sound waves travel through the vibration of particles in a medium. The wavelength of a sound wave is the distance between two consecutive points of similar phase. When sound travels over a long distance, it tends to spread out and become less intense. This phenomenon, known as sound attenuation, is more pronounced for sound waves with longer wavelengths. Therefore, the fact that sound cannot travel through a far distance suggests that it has long wavelengths.
