Question on: SS1 Physics - Sound And Waves

Reflection of sound waves occurs when sound encounters a surface and bounces back. The angle of incidence is equal to the angle of reflection. For example, when a person shouts in front of a large flat wall, the sound waves bounce off the wall and reach the person's ears as reflected sound. The intensity of the reflected sound depends on factors such as the nature of the surface (smooth or rough), the angle of incidence, and the distance between the source and the reflecting surface. A smooth, hard surface reflects sound more efficiently, resulting in a higher intensity of reflected sound.
