CONCEPT:

  • Wave motion: The type of disturbance that travels through a medium due to repeated vibrations of the particles of the medium about their mean positions is called wave motion.

There are two types of wave motion:

  • Longitudinal wave motion: It is that wave motion in which individual particles of the medium execute simple harmonic motion about their mean position along the same direction, in which the wave is propagated.
    • For example: Sound waves
  • Transverse wave motion: Vibration of particles in a medium and the propagation of wave are perpendicular to each other.
    • Example: Waves in the surface of the water, waves in a string, light waves, etc.

EXPLANATION:

  • Light wave is a transverse wave. 
  • The radio wave is also a type of light. So it is a transverse wave.
  • Sound is a longitudinal wave and ultrasound is also a type of sound wave. So ultrasound is the longitudinal wave. Hence option 3 is correct.
  • Surface water waves is a transverse wave.
