Question

PHYS 203 Name: Ray Tracing Name: Work in pairs. Turn in one copy per pair Part A: Ray Tracing (18 pts) For each of the following situations, draw the three principle rays and find the image. Measure, f.p. q. h and h and label them below (1 "large box" 1.0 cm). Indicate whether the image is: - real or virtual upright or inverted - enlarged or reduced - in front or behind the mirrorlens No pens allowed. Draw this in pencil. Remember, your principle rays are: Mirrors Ray parallel to the principal axis reflects through the focal point. 2. 1. Ray through the canter of curvature reflects back through the center of curvature. 3. Ray through the focal point reflects back parallel to the principal axis Lenses 1. Ray parallel to the principal axis refracts through the focal point (far for converging, near for diverging) 2. Ray through the center of the lens is un-deflected. 3. Ray through the focal point (near for converging, far for diverging) refracts parallel to the principal axis. 1. Concave mirror, object outside focal point. 2. Concave mirror, object inside focal point. 3. Convex mirror 4. Converging lens, object outside focal point. Converging lens, object inside focal point. 5. 6. Diverging lens B. Verify the mirror/lens equation (17 pts) In the space below (and on the next page), use the mirror/lens equations and the magnification equations to verify the locations and sizes of your image for each of your six cases. Make sure the sign conventions are used correctly
