Reflection of light ---> Spherical Mirrors Chapter 3

Concave and Convex mirrors and diagrams

curves in at the center

Concave Mirror

Bulges at the center

Convex mirror

Centre of a spherical mirror

the pole

Centre of the sphere the mirror is made of

the centre of curvature

halfway between the centre of curvature and the pole is

The focus

angle of incidence is equal to

angle of reflection

angle of reflection is equal to

angle of incidence

a ray which strikes the pole

reflected back at the same angle equal to the axis

a ray passes through
h the centre of curvature

goes back on itself

a real image is formed

by the actual intersection of light rays

virtual image is formed

by the apparent intersection of light rays

1/u + 1/v =

1/f

U

object distance from mirror

v

image distance from mirror

f

Focal lenth

law of reflection 1

angle of incidence equals law of reflection

law of reflection 2

the incidence ray reflected ray and the normal at the point of incidence are all in the same plane
