Question

Free coherent waves of equal frequency having executed 10 m u m m 40 m per second respectively the given. 666

Answer 1

Answer:

The amplitude of the resulting wave is 5 mm.

Explanation:

Given that,

Amplitude

Amplitude

Amplitude

Phase difference

Let the waves be

Using superposition theorem

The resultant disturbance is given by

Let R be the resultant amplitude

Hence, The amplitude of the resulting wave is 5 mm.
