A lighted candle is placed 38.0 cm in front of a diverging lens. The light passes through the diverging lens and on to a converging lens of focal length 14.0 cm that is 6.0 cm from the diverging lens. The final image is real, inverted, and 42.0 cm beyond the converging lens. Find the focal length of the diverging lens.

3. Optics problem set: a) [6 pts) An incident light ray in air strikes a glass prism as shown. Sketch the ray diagram with the light rays refracted through each glass boundary. There is no total internal reflection in this problem. This ray diagram should include (1) normal lines, and (2) the qualitatively correct directions of refracted rays. b) [6 pts) Two converging lenses (#1 and #2) are given with an object as an arrow below. A pair of focal...
1.)
Parallel light rays pass through a concave lens as illustrated in
figure 1. Using the diagram, indicate the focal point of this lens.
2.) A convex lens has a focal length of 100 mm. The lens
produces an image from an object placed 50 cm from the lens.
Determine the distance from the lens to the image in the
magnification of the image.
