Detailed Solution

Amplitude of the transmitted wave, $A_{t} = (\frac{2 K_{1}}{K_{1} + K_{2}}) A_{i} = (\frac{2 V_{2}}{V_{2} + V_{1}}) A_{i}$

${If μ}_{1} > μ_{2}, V_{2} > V_{1} If μ_{1} < μ_{2}, V_{1} < V_{2}$

When an incident wave encounters a boundary or interface between two different media, such as when light waves hit a mirror or sound waves strike a wall, some of the incident wave's power is divided into reflected and transmitted waves. This phenomenon is governed by the principles of wave behavior, such as the law of reflection and the law of refraction.

Power of incident wave is divided into reflected and transmitted waves.
