    What is nature of light and sound waves?

    A)  Light is transverse and sound is longitudinal

    B)  Light is longitudinal and sound is transverse

    C)  Both are transverse

    D)  Both are longitudinal

    Correct Answer: A

    Solution :

     In transverse wave motion the particles of the medium oscillate about their mean or equilibrium position at right angle to the direction of propagation of wave motion itself. In longitudinal wave motion the particles of the medium oscillate about their mean or equilibrium position along the direction of propagation of the wave motion itself. Light waves are transverse in nature whereas sound waves are longitudinal.
