Sunlight is observed to focus at a point 30 cm behind a lens. (a) Draw a ray diagram for this situation. (The sun is so far away that you can consider all of the incoming rays to be parallel to each other.) (b) Is the lens converging or diverging? (c) Is the lens convex or concave? (d) What is the lens’s focal length in meters? (e) What is its focusing strength in diopters? (And is it positive or negative?)

A converging lens has 31.4 cm focal length, and is placed 21.0 cm behind a diverging lens. Parallel light strikes the diverging lens. After passing through the converging lens, the light is again parallel. What is the focal length of the diverging lens in cm? (Hint: draw a ray diagram)

Part A: A diverging lens has of focal length of 15.0 cm. An object is placed 21 cm to the left of the lens. a) draw a ray diagram showing the situation. b) find the location of the image produced by the lens (mind the signs). Part B: A converging lens is located 30 cm to the right of the previously mentioned diverging lens (part A). As a result, the image you found in part (a) is now instead located...

A 4.0 cm tall object is 5.0 cm in front of a diverging lens with a focal length of -6.0 cm. A converging lens with a focal length of 6.0 cm is located 8.0 cm behind the diverging lens. (As viewed from the side, from left to right, the sequence is object - diverging lens - converging lens - observer. Rays then travel from left to right through the system.) (a) Use ray tracing to draw image 1 and image...
