Which one of the following statements is true?

  1. A
    Both light and sound waves in air are transverse
  2. B
    The sound waves in the air are longitudinal while the light waves are transverse
  3. C
    Both light and sound waves in air are longitudinal
  4. D
    Both light and sound waves can travel in a vacuum

Solution & Step-by-step Explanation

Sound waves require a material medium and travel as compressions and rarefactions in air, making them longitudinal waves. Light waves are electromagnetic waves composed of oscillating electric and magnetic fields perpendicular to the direction of propagation, making them transverse. Sound cannot travel in a vacuum, whereas light can.
