- Now imagine the following new situation, butdon’t actually do it yet. Suppose you lay the
mirror face-up on a piece of tissue paper, put your finger a few cm above the mirror, and look
at the image of your finger. As in part 2, you can bring your eye closer and closer to the mirror.
Will you be able to see the image with your eye very close to the mirror? Draw a ray diagram
to help you predict what you will observe.
Prediction:
Now test your prediction. If your prediction was incorrect, see if you can figure out what went
wrong, or ask your instructor for help.- For parts 4 and 5, it’s more convenient to use concave mirrors that are more gently curved;
obtain one from your instructor. Lay the mirror on the tissue paper, and use it to create an
image of the overhead lights on a piece of paper above it and a little off to the side. What do
you have to do in order to make the image clear? Can you explain this observation using a ray
diagram?
