Mirrors and Reflection of Light

Mirror - Any surface smooth enough to produce a regular reflection of light incident upon it

Plane Mirror - Mirror with a flat surface

Spherical Mirror - Mirror with a reflecting surface taken from the surface of a sphere

Concave Mirror - Mirror that curves inwards in the direction of the incident rays

Convex Mirror - Mirror that bulges outward to the incident rays

Real Image - Formed by actual intersection of reflected rays

Virtual Image - Image formed behind the mirror and is upright relative to the object

Center of Curvature(C) - Center of sphere where mirror was taken

Radius of curvature - Radius of the sphere

Principal Axis - Straight line joining C and V

Center of the mirror - Vertex

Focus(F) - Point where reflected rays meet

Focal Length - Distance from the vertex to the principal focus

Magnification - Size of the image relative to the object

Reflection - Bouncing back of light to the original medium where it has been traveling after striking a surface

Formulas:

Magnification = Si/So = -di/do

1/F = 1/do + 1/di
