1

concave mirror

a mirror where the reflecting surface curves inward

2

principle axis

the line that passes through the centre of curvature
normal to the centre of the mirror

3

centre of curvature (C)

the point where all normals meet

4

vertex (V)

the point where the principal axis cuts the centre of the mirror

5

focal point (F)

where incident rays are near and parallel to the principle axis, their reflected rays all pass through the same point on the principle axis
this point is the focal point

6

focal length (f)

the distance between the vertex and the focal point

7

radius of curvature (R)

the distance between the vertex and the centre of curvature

8

when an incident ray travels parallel to the principle axis, it is reflected ____________

through the focal point

9

when an incident ray passes through the focal point (F), the reflected ray is parallel _____________

to the principle axis

10

when an incident ray passes through the centre of curvature (C), it is reflected _______________

back onto itself

when an incident ray strikes the vertex (V), the principle axis is ________

its normal
