What is the phenomenon of bending of light when it passes from one medium to another called? (2015)

Step 1: Understand that light travels in straight lines in a uniform medium.
Step 2: Know that a medium is a substance through which light can travel, like air, water, or glass.
Step 3: Recognize that when light moves from one medium to another (like from air to water), its speed changes.
Step 4: Realize that this change in speed causes the light to bend at the boundary between the two media.
Step 5: Learn that this bending of light is called refraction.
