Reflection

Various types of mirrors, including concave, plane, triple corner, and convex mirrors, each serve distinct purposes based on their reflective properties and structural designs. Concave mirrors are often used in applications like magnifying glasses and telescopes due to their ability to create real images.

Reflection

Specular

Diffuse

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

Smooth and flat surfaces

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

Reflection

Description of image

Type
Location
Attitude
Size

Laws

The reflected ray, the normal and the incedent ray all lie on the same plane
The refelcted ray and incedent ray are on opposite sides of the normal
The angle of reflection (r) = the angle of incidence (i)

Concave Mirrors

creates a real image
Magnifying glasses
Teloscopes
cosmetic or magnifying mirrors

Plane Mirrors

To check appearances
Object distance (di) in front of the mirror = Image disntance (di) behind the mirror
Any smooth, flat, reflecting surface

Triple Corner Mirrors

Retroflection
Light rays bouncing off and shining back to the source
Applications
Reflective clothing
Reflective signs

Convex Mirrors

Takes up a smaller angle and looks smaller
Aplications
Car mirrors
Security Mirrors
Car headlights
