To solve the problem, we need to find the ratios of the amplitudes of the reflected and transmitted waves compared to the incident wave when a progressive wave travels from medium \( M_1 \) to medium \( M_2 \) with a speed decrease to 75%. ### Step-by-Step Solution: 1. **Identify the given information:** - The speed of the wave in medium \( M_1 \) is \( V_1 \). - The speed of the wave in medium \( M_2 \) is \( V_2 = 0.75 V_1 \). ...
