Reflection

Convex Mirrors

Car headlights

Security Mirrors

Car mirrors

Takes up a smaller angle and looks smaller

Triple Corner Mirrors

Applications

Reflective signs

Reflective clothing

Retroflection

Light rays bouncing off and shining back to the source

Plane Mirrors

Any smooth, flat, reflecting surface

Object distance (di)
in front of the mirror
= Image disntance (di)
behind the mirror

Aplications

To check appearances

Car mirrors

Concave Mirrors

creates a real image

Laws

The angle of reflection (r) = the angle of incidence (i)

The refelcted ray and incedent ray are on opposite sides of the normal

The reflected ray, the normal and the incedent ray all lie on the same plane

Description of image

Location

Type

Specular

Smooth and flat surfaces

All normals are perpendicular to the surface < i = < r

Diffuse

Rough surfaces

The normals are all facing different directions
< r are all different from each other
