Question

A transverse wave traveling along a string transports energy at a rate r. If we want to double this rate, we could: _____________

a. increase the amplitude of the wave by a factor of 8.
b. increase the amplitude of the wave by a factor of 4.
c. increase the amplitude of the wave by a factor of 2.

Answer 1

We will increase the amplitude of the wave by a factor of 4 If we want to double this rate

Transverse wave energy travel

Transverse wave, travels in a way in which points on a wave oscillate along paths at right angles of 90 degrees to the direction of the wave.

We see that energy transported along a wave path is directly proportional to the square of the amplitude.

E =kA^2

Therefore, we will increase the amplitude of the wave by a factor of 4 If we want to double this rate.
