Principles of light: When light hits a surface, it bounces off at a certain angle and the angle that the light hits the surface (or the angle of incidence) determines how light bounces off. But the mirror doesn't alter the incoming beams of light so the light rays bounce back! The image from a flat mirror is a virtual image because it can't be focused, and the rays aren't coming out at straight lines. The rays hit our eyes and allow us to see our reflection BUT... its not actually there!
Convex vs. Concave mirrors
Convex mirrors are mirrors that go out and cause the reflection to look bigger. Makes a virtual image. The image is formed behind the lens unlike a concave mirror. Light rays never converge in front of the lens

Concave mirrors are mirrors the go in (*cave in*) They cause the reflection/ Real Image to invert, or appear up side down. Light rays reflect off mirror.
