Questions Related to sound waves are longitudinal waves

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.

When we pluck the wire of a sitar, the waves produced in the wire are

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

  1. Longitudinal

  2. Transverse

  3. Sometimes longitudinal and sometimes transverse

  4. Electromagnetic

Show answer
Correct Option: B
Explanation:

A transverse wave is a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the yz plane. In any pluck string instrument we are actually doing the same.

A transverse wave is a wave that consists of oscillations that are 

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

  1. parallel to the direction of wave propagation

  2. perpendicular to the direction of wave propagation

  3. radial to the direction of wave propagation

  4. none of the above

Show answer
Correct Option: B
Explanation:

A transverse wave is a wave that consists of oscillations that are perpendicular to the direction of wave propagation

The correct option is (b)

A loaded spring produces __________ waves.

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

  1. Transverse

  2. Longitudinal

  3. Both (A) and (B)

  4. None of the above

Show answer
Correct Option: B
Explanation:

loaded spring  applies force only in axial direction of the spring and the movement is also axial so the waves produced are longitudinal waves.

so the answer is B.

In a transverse wave, the distance between a crest and the immediate trough is $\frac{\lambda}{2}$.

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:

the distance between two either consecutive troughs or troughs is called wavelength and between a trough and a immediate crest is half of wavelength .

so the answer is A.

Which property in a medium changes, when a longitudinal wave passes through it

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

  1. Pressure

  2. Mass

  3. Velocity

  4. Acceleration

Show answer
Correct Option: A
Explanation:

The pressure in a medium varies as a longitduinal wave passes through the medium

The correct answer is (a)
