Which one of the following statements is true?

Options

  1. ABoth light and sound waves in air are longitudinal.
  2. BBoth light and sound waves in air are transverse.
  3. CBoth light and sound waves can travel through vacuum.
  4. DThe sound waves in air are longitudinal while the light waves in air are transverse.

Correct answer

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

Step-by-step solution

Sound waves in air are mechanical waves that propagate through compressions and rarefactions, making them longitudinal waves. Light waves are electromagnetic waves consisting of oscillating electric and magnetic fields perpendicular to the direction of propagation, making them transverse waves. Therefore, sound waves in air are longitudinal while light waves are transverse. Answer: The sound waves in air are longitudinal while the light waves in air are transverse.
