Question

What is one way to increase the amplitude of a wave in a medium?

Answer 1

Can u tell me wt is amplitude?

Answer 2

Using the formula v=f*lambda, you can see that f varies inversely as the lambda, hence decreasing the frequency increases the lambda.

Answer 3

If you are asking how can the amplitude be increased while it exists in a medium, one way is by constructive interference from another wave of same phase.
