Ray Tracing for Spherical Mirrors

What are the three rays neded to find the image position and size for spherical mirrors?

1. Rays parallel to the axis are relfected through the focal point F
2. Rays passing through the focal point are reflected parallel to the axis


1. Rays passing through the centre-of-curvature are refleccted back on themselves

Where is the image reflected in a concave mirror?

In front of the mirror, real image

Where is the image reflected in a convex mirror?

Behind the mirror, virtual image

What is r?

radius of curvature

What is f?

focal length

What is u?

object distance

What is v?

image distance
