Reflection is when light bounces off a surface and returns into the same medium, like a mirror sending your image back to your eyes. The angle at which light hits equals the angle at which it leaves. Refraction happens when light passes from one medium to another, like air to water, and changes speed, causing it to bend. This bending makes objects under water look shifted. Reflection changes direction at a surface, refraction changes direction inside materials. Want more interesting content like this ?
