Questions Related to study of sound

The moon is at a distance of $4\, \times\, 10^8\, m$ from the earth. What is the nature of radar signal transmitted from earth?

physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

  1. Remain fixed

  2. Vibrate to and fro about their mean position

  3. Move along the wave

  4. Change their positions permanently

Show answer
Correct Option: B
Explanation:

radar signal is a example of EM wave . so the signal will vibrate to and fro about mean position

so the answer is B.

The angle between particle velocity and wave velocity in a transverse wave is

physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

  1. zero

  2. $\pi /4$

  3. $\pi /2$

  4. $\pi$

Show answer
Correct Option: C
Explanation:

In a transverse wave, the displacement of the particle is perpendicular to the wave propagation. Thus, the angle between particle velocity and wave  velocity should be $\pi/2$.

The waves in which the particles of the medium vibrate in a direction perpendicular to the direction of wave motion is known as

physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

  1. Longitudinal waves

  2. Propagated waves

  3. Transverse wave

  4. None of these

Show answer
Correct Option: C
Explanation:

Transverse waves have particles oscillating perpendicular to the direction of motion of wave. Ripple in the surface of water is transverse in nature

The waves which can propagate in metals are :

physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

  1. longitudinal waves

  2. transverse waves

  3. both (a) and (b)

  4. neither (a) nor (b)

Show answer
Correct Option: C
Explanation:

Propagation of waves depends on the medium through which they propagate. Transverse wave need a medium rigid enough which neither liquid nor gas can provide and hence transverse wave can travel through metals. For longitudinal wave they just require a medium for propagation. Hence transverse and longitudinal wave can both propagate in metals.

Wave in which particles of the medium oscillate to and from about their mean position is

physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

  1. Transverse wave

  2. Longitudinal wave

  3. Oscillatory wave

  4. None

Show answer
Correct Option: B
Explanation:

By definition a wave in which the particles of the medium oscillate to and fro about their mean positions in the direction of propagation is known as longitudinal wave. It can be produced in any medium.

Disturbance produced in a material medium due to the vibratory motion of the particles of the medium is called a

physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

  1. compression

  2. vibration

  3. wave

  4. rarefaction

Show answer
Correct Option: C
Explanation:

In wave motion, particles of the medium vibrate about their mean positions. The particles of the medium do not move from one place to another

The waves produced in a spring by compressing a small portion of it and releasing are

physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

  1. transverse waves

  2. longitudinal waves

  3. oscillatory waves

  4. non material waves

Show answer
Correct Option: B
Explanation:

Waves produced in a spring by compressing a small portion of it and releasing are longitudinal waves.

Compression and rarefaction are seen in

  1. Transverse waves

  2. Non mechanical waves

  3. Longitudinal waves

  4. None

Show answer
Correct Option: C
Explanation:

Compression and rarefaction are seen in longitudinal waves

The waves in which the particles of the medium vibrate in a direction perpendicular to the direction of wave motion is known as

physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

  1. Transverse wave

  2. Propagated waves

  3. Longitudinal waves

  4. Stationary waves

Show answer
Correct Option: A
Explanation:

In transverse waves, particle of the medium vibrate in a direction perpendicular to the direction of wave motion.

State whether the given statement is True or False :
The ripples in water waves are created by the oscillatory movement of water particles.
physics study of sound types of waves sound as a wave of disturbance sound waves are longitudinal waves

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

We know that a transverse wave consists of successive crests and troughs. In a  transverse wave, the particles of the medium oscillate in a direction perpendicular to the direction of propagation.

We can easily see that the ripples in water are transverse in nature. They are created due to the oscillation of the water particles.
