Question

Which of the following best describes refraction of a wave?A. As a wave moves around a corner or through an opening, itsdirection of motion changes.B. As a wave reaches the interface between two different media, itsdirection of motion changes and it remains in the first medium.C. As a wave moves from one medium to another, the energy of thewave is converted to other forms of energy.O D. As a wave moves from one medium into another in which itsspeed is different, the wave changes direction.

Answer 1

Refraction is the phenomenon in which waves change their path of propagation at the interface of two media with different densities. When a wave moves from one medium into another in which its speed is different, the wave changes direction.

Step-by-step explanation:

Refraction is the phenomenon in which waves change their path of propagation at the interface of two media with different densities. When a wave moves from one medium into another in which its speed is different, the wave changes direction. This change in direction occurs because the wavefronts of the wave travel at different speeds, causing the wave to bend.
