What is the difference between reflection and refraction of light?

• Reflection is the bouncing back of light when it hits a surface, while refraction is the bending of light as it passes from one medium to another.

• Reflection is the bending of light as it passes from one medium to another, while refraction is the bouncing back of light when it hits a surface.

• Reflection and refraction are the same thing, just different terms used in different contexts.

• Reflection and refraction both refer to the absorption of light by a surface.
