Question

Density variations are not caused among the particles of the medium when they vibrate ____ the direction of the wave propagation.

  1. In
  2. At 30-degree angle to
  3. At 90-degree angle to
  4. At 135-degree angle to

Hint:

Pressure and density variations are seen in a longitudinal wave, where the particles of the medium vibrate parallel to the direction of wave propagation.

The correct answer is: At 90-degree angle to


    • Pressure and density changes do not occur in a transverse stationary wave.
    • In a transverse wave, particles of the medium vibrate and move in a direction perpendicular to the direction of wave propagation.
    • So, the correct option is c.
