Questions Related to sound waves are longitudinal waves

Which of the following is not a longitudinal wave?

  1. Seismic P-wave

  2. Light

  3. Sound

  4. Ultrasound


Correct Option: B
Explanation:

In case of light, the waveform changes perpendicular to the relative motion. So, it is a type of transverse wave, which causes the medium to vibrate perpendicular to the wave energy .

Light waves are transverse in nature.

  1. True

  2. False


Correct Option: A
Explanation:

light is a EM wave and has transverse nature .

so the answer is A.

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

  1. perpendicular to the direction of wave propagation

  2. parallel to the direction of wave propagation

  3. radial to the direction of wave propagation

  4. none of the above


Correct Option: B
Explanation:

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

The correct option is (b)

In a longitudinal wave, the density of particles is more at a compression.

  1. True

  2. False


Correct Option: A
Explanation:

in longitudinal waves at compressions density is high and at rerefactions the particle density is low.

so the answer is A.
