Questions Related to sound as a wave of disturbance

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

The waves produced by a motor boat sailing in water are

  1. transverse

  2. longitudinal

  3. longitudinal and transverse

  4. stationary
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When a motor boat sails in water , waves will be produced on the surface of the water. We know that water waves are a combination of longitudinal and transverse waves as the particles move in a circular path.

Energy is not carried by 

  1. Transverse progressive waves

  2. Longitudinal progressive waves

  3. Stationary waves

  4. Electromagnetic waves
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

$Answer:-$ C option

All the propagating waves (wave on string -transverse , sound-longitudinal)  carry energy with them and also electromagnetic waves like light carry energy.
Stationary waves do not carry energy with them because their energy is confined in that area (as they are not propagating).

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

Waves inside a gas are

  1. Longitudinal

  2. Transverse

  3. Partly longitudinal, partly transverse.

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

$Answer:-$ A option

In fluids (liquids and gases), atoms have no "equilibrium location"; they can move freely past each other. So if one atom gets moved by a disturbance, there's no restoring force to pull it back to its equilibrium location,
hence transverse waves cannot travel through fluids.
so only longitudinal waves can travel in gases and liquids.

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?

  1. Remain fixed

  2. Vibrate to and fro about their mean position

  3. Move along the wave

  4. Change their positions permanently
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

Multiple choice physics study of sound types of waves sound as a wave of disturbance sound waves are 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

  1. Longitudinal waves

  2. Propagated waves

  3. Transverse wave

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
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 :

  1. longitudinal waves

  2. transverse waves

  3. both (a) and (b)

  4. neither (a) nor (b)
Reveal answer Fill a bubble to check yourself
C Correct answer
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.

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

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

  1. Transverse wave

  2. Longitudinal wave

  3. Oscillatory wave

  4. None
Reveal answer Fill a bubble to check yourself
B Correct answer
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.
