Wave a has an amplitude of 3, and wave b has an amplitude of 3. what will happen when the trough of wave a meets the trough of wave b?

Explanation:

It is given that both wave have same amplitude i.e

Now, we need to find what will happen to the waves when trough of wave A meets the trough of wave B.

It means that both waves are in same phase i.e, the phase difference between them is 0 degree.

We know resultant amplitude of two waves of same amplitude A with phase difference is given by.

In this case , A=3 and

Putting value of A and in above equation.

We get,

Therefore, a new wave will form of resultant amplitude of 6.

Hence, it is the required solution.
