In case of reflection of sound waves

WebAnother important case in which sound waves bend or spread out is called refraction. This phenomenon involves the bending of a sound wave owing to changes in the wave’s … When a wave reaches the boundary between one medium another medium, a portion of the wave undergoes reflection and a portion of the wave undergoes transmission across the boundary. As discussed in the previous part of Lesson 3, the amount of reflection is dependent upon the dissimilarity of the two media. … See more Diffraction involves a change in direction of waves as they pass through an opening or around a barrier in their path. The diffraction of water waveswas discussed in Unit 10 of The … See more Refraction of waves involves a change in the direction of waves as they pass from one medium to another.

The redirection can be caused by the wave's change in speed or by a change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.
