1. An object of height 2 cm is placed 10 cm in front of a mirror. What type of mirror with what radius of curvature is needed to create an upright image with a height of 5 cm?
2. A ray of light strikes the midpoint of one face of an equilateral glass prism (n = 1.6) at an angle of incidence of 50°. Trace the path of the ray through the glass and find the angles of incidence and refraction at each interface. Ignore any dispersion that might take place.
3. A converging lens of focal length 10 cm is placed 35 cm in front of a concave mirror with a radius of curvature of 20 cm. An object is placed 13 cm in front of the lens. Locate and describe the final image, and determine its net magni?cation. (ray diagram not required)
4. A ray of light passes between layers of material as shown. Find the minimum value for θ2 and the corresponding value of θ1 that will result in total internal reflection at the glass/air interface.
