The incident wave amplitude is 24 units. Find the reflected wave amplitude if the reflection coefficient is 0.6.

The incident wave amplitude is 24 units. Find the reflected wave amplitude if the reflection coefficient is 0.6. Correct Answer 14.4

The reflection coefficient is the ratio of the reflected amplitude to the incident amplitude. Thus R = Er/Ei. On substituting for Ei = 24 and R = 0.6, we get Er = R Ei = 0.6 X 24 = 14.4 units.
