Chapter 23, Problem 37P
Dentist lamps Dentists use special lamps that consist of a concave mirror and a small, bright light source that is fixed on the principal axis of the mirror. When the light source is placed 5.0 cm from the mirror, the reflected light is focused in a bright spot at distance 70.0 cm from the mirror. Determine the radius of curvature of the mirror.
