PHYSICS 6C Ch.24 Worksheet Solutions clas.ucsb.edu/staff/vince/ 1) The reflecting surfaces of two plane mirrors form an angle of 120°. If a ray of light strikes mirror 1 with an angle of 55°, find the angle of reflection when the light leaves mirror 2. 2) Sunlight reflects from a concave piece of broken glass, converging to a point 15 cm from the glass. What is the radius of curvature of the glass? This is a concave mirror, so the radius is positive, and double the focal length. The sunlight is coming from a distant object (S= ∞), so the image is at the focal point. So R=+30cm . 3) An object with a height of 42cm is placed 2.0m in front of a convex mirror with a focal length of -0.5m. Find the location and size of the resulting image. Is this image real, or is it virtual? Use the standard thin lens formula with S=2m and f=-0.5m. m 4 . 0 S 2 1 5 . 0 1 S 1 S 1 S 1 f 1 This is a virtual image, 40cm behind the mirror. For size, use cm 4 . 8 ) 2 4 . 0
