# Refraction, Radius of curvature

1 A light ray from air is incident on Fabulite. The speed of light in the Fabulite is 1.245x10^8 m/s. At what angle would the incident ray have struck the surface if it was found to have a refracted angle of 12 degrees in the Fabulite?

2. A makeup mirror is designed so that a person 25 cm in front of it sees an erect image magnified by a factor or two.

a) What is the radius of curvature of the mirror?

b) Is the mirror concave or convex?
