The tendency of sound waves to bend when they pass from one medium to a different medium is known a refraction.
<h3>What is refraction ?</h3>
In diffraction, a sound wave is bent or stretched out in a single medium where the sound speed remains constant. Refraction is a crucial instance in which sound waves arc or diffuse. Due to variations in the wave's speed, a sound wave bends in this occurrence.
A wave bends as it travels along the edge of an object or through an aperture. It is referred to as diffraction. When a wave transitions from one medium to another at an angle, it also bends. It's known as refraction.
Thus, The option A is correct.
