Question: Locate two small plane mirrors like the ones often carried in a purse. Place the two mirrors next to each other so that they touch

Locate two small plane mirrors like the ones often carried in a purse. Place the two mirrors next to each other so that they touch along one edge, making an angle of 90° between the two mirrors. Place a small object like a paper clip in front of the two mirrors.
a. How many images do you see in the two mirrors when the angle between the mirrors is a right angle (90°)?
b. As you decrease the angle between the two mirrors, describe what happens to the number of images that you can see.
c. Using the idea that each of the images formed can serve as an object for the other mirror, can you explain your observations? (Ray diagrams may be useful.)
