Which one of the following statements is true?

Which one of the following statements is true?

Options

  1. ABoth light and sound waves in air are transverse
  2. BThe sound waves in air are longitudinal while the light waves are transverse
  3. CBoth light and sound waves in air are longitudinal
  4. DBoth light and sound waves can travel in vacנum

Correct answer

B. The sound waves in air are longitudinal while the light waves are transverse

Step-by-step solution

Sound wave is longitudinal because the medium particles move parallel to the direction of wave propagation, whereas a light wave is transverse because the medium particles move perpendicular to direction of wave propagation. Hence, option 2 is correct.
