The phenomenon of change in direction of light when it passes from one medium to another is called
Refraction
The change in direction of light when it transitions from one medium to another is known as refraction. This phenomenon occurs because light travels at different speeds in different media. When light enters a medium at an angle, it bends due to the change in speed, resulting in a change of direction. This bending or changing direction of light is what defines refraction, distinguishing it from other optical phenomena such as reflection, where light bounces off a surface without significantly changing its speed or direction within the new medium.
