Questions: Which statement about transverse waves is correct? In transverse waves, particles of the medium a vibrate back and forth parallel to the direction of the wave. b Transverse waves do not require an energy source. c Transverse waves are a type of mechanical wave. d Transverse waves are the same as surface waves.

Solution Steps

Transverse waves are characterized by particle motion that is perpendicular to the direction of wave propagation. This is a key feature that distinguishes them from longitudinal waves, where particle motion is parallel to the wave direction.

• Statement a: "In transverse waves, particles of the medium vibrate back and forth parallel to the direction of the wave."
  This statement is incorrect because, in transverse waves, particles vibrate perpendicular, not parallel, to the direction of wave propagation.

• Statement b: "Transverse waves do not require an energy source."
  This statement is incorrect. All waves, including transverse waves, require an energy source to be generated and propagated.

• Statement c: "Transverse waves are a type of mechanical wave."
  This statement is correct. Transverse waves can be mechanical, such as waves on a string or surface water waves, although not all transverse waves are mechanical (e.g., electromagnetic waves).

• Statement d: "Transverse waves are the same as surface waves."
  This statement is incorrect. While surface waves can have transverse components, they are not purely transverse waves. Surface waves are a combination of transverse and longitudinal wave motions.
