A progressive wave travels in a medium

M_1

and enters into another medium

M_2

in which its speed decreases to

75 \%

. What is the ratio of the amplitude and intensity of the

a. Reflected and the incident waves, and

b. Transmitted and the incident waves?

View answer and explanation

Correct option: A

\frac{36}{49}

Option A (

\frac{36}{49}

) is correct because it represents the ratio of the intensity of the reflected wave to the incident wave, calculated using the reflection coefficient.
