Question

Two harmonic waves travelling in the same medium have frequency in the ratio 1: 2 and intensity in the ratio 1: 36. Their amplitude ratio is: (A) 1: 6 (B) 1: 8 (C) 1: 72 (D) 1: 3

Tardigrade Admin · Accepted Answer

As we know that intensity of a wave is directly proportional to square of frequency as well as square of amplitude.
