    The phenomenon of beats can take place
    (a) for longitudinal waves only
    (b) transverse waves only
    (c) for both longitudinal and transverse waves
    (d) for sound waves only.
    digAnsr:   c
    Ans : (c) for both longitudinal and transverse waves
    When two or more waves of slightly different frequencies (v1 - v2 ≯ 10) travel with the same speed in the same direction, they superimpose to give beats. Thus, the waves may be longitudinal or transverse.
