I just want to check my answers for this pre-lab. Help would be fantastic!
1. In each of the three situations shown, parallel rays of light are incident on one or more pieces of transparent plastic. In each case, continue the rays through the plastic and out the other side. Make your diagrams qualitatively correct.
2. Parallel rays of light are incident on two pieces of plastic. Each piece has one flat side and one curved side. The pieces of plastic are of different thickness.
For each case below, continue the rays through the plastic and out the other side, In which case do the rays emerging from the plastic converge at a point that is closer to the surface of the plastic?
3. An object is placed near a converging lens as shown below. Each focal point is marked by an F. Two rays have been drawn to determine the location of the image of the object. Continue the third ray shown through the lens and out the other side. Explain how you determined your answer.
4. A converging lens, a long filament bulb are arranged as shown in the perspective view diagram below. A sharp, inverted image of the filament of the bulb appears on the screen when it is at the location shown. Describe how, if at all, the image on the screen would change if the top half of the lens were covered by an opaque mask. Explain your reasoning.
