A light Ray is an imaginary line that Ravens in the direction of light.

A virtual image is a image from a bend of light not the actual light path.

A real image is a virtual image behind a mirror.

Diffuse reflection is reflecting light in a random direction.

Geometrical optics are light behaving like waves.

The angle of reflection is light reflecting off of something.

The angle of incidence is light rays striking the surface.

Normal is where the light hits the mirror.

A convex mirror is a mirror that bulges out.

A concave mirror is a mirror that is indented.
