Bulges at the center
Convex mirror
3
New cards
Centre of a spherical mirror
the pole
4
New cards
Centre of the sphere the mirror is made of
the centre of curvature
5
New cards
halfway between the centre of curvature and the pole is
The focus
6
New cards
angle of incidence is equal to
angle of reflection
7
New cards
angle of reflection is equal to
angle of incidence
8
New cards
a ray which strikes the pole
reflected back at the same angle equal to the axis
9
New cards
a ray passes through
h the centre of curvature
h the centre of curvature
goes back on itself
10
New cards
a real image is formed
by the actual intersection of light rays
11
New cards
virtual image is formed
by the apparent intersection of light rays
12
New cards
1/u + 1/v =
1/f
13
New cards
U
object distance from mirror
14
New cards
v
image distance from mirror
15
New cards
f
Focal lenth
16
New cards
law of reflection 1
angle of incidence equals law of reflection
17
New cards
law of reflection 2
the incidence ray reflected ray and the normal at the point of incidence are all in the same plane
