NEETPhysicsWavesMCQ+4 / −1
Which one of the following statements is true ?
  1. A
    both light and sound waves can travel in vaccum
  2. B
    both light and sound waves in air are transverse
  3. C
    The second waves in air are longitudinal while the light waves are transverse
  4. D
    both light and sound waves in air are
View written solutionFree

Correct answer: C

Light waves are electromagnetic waves. Light waves are transverse in nature and do not require a medium to travel, hence they can travel in vacuum. Sound waves are longitudinal waves and require a medium to travel. They do not travel in vacuum.
