Concave/ Converging Mirror

Question 1

C=

Answer 1

Center of curvature: the center of the sphere whose surface has been used to make the mirror

Question 2

PA=

Answer 2

Principle of Axis: line through the center of curvature and mirror. It intersects the mirror at 90 degrees and is normal to the surface

Question 3

V=

Answer 3

Vertex: the point where the principle axis intersects the mirror

Question 4

F=

Answer 4

Focal point: the point light rays parallel to the principal axis converge when reflected off a concave mirror

Question 5

3 light ray rules

Answer 5

1. A light ray shone parallel to PA reflects back through F
2. A light ray that is shone through F will reflect back parallel to PA
3. A light ray shone through C will reflect back through C

Question 6

All concave mirrors will have what SALT characteristic in common

Answer 6

The type which will always be Real
