What is the difference between reflection and refraction?

Reflection is when light bounces off an object, while refraction is when light bends while passing through an object.

When you look at a mirror the light bounces of the mirror from different angles, so you can see your reflection. If you point light or a laser pointer at a mirror, it will reflect to the wall in front of the mirror. Refraction is when light bends. For example, When there is a rainbow in the sky, the light from the sun is being refracted from the particles of water and splits the light up into different colors. Try shining a light in a clear prism!
