Question

7. The diagram below shows an arrow, plane mirror, and observer. As you know fro image of the arrow will appear behind the mirror mirror Observer Suppose the observer moves two feet backwards, away from the mirror. a) Will the location of the image move or stay the same? b) Will the size of the image increase, decrease, or remain the same? c) Will the angular size of the image increase, decrease, or remain the same? Suppose the observer moves two feet to the right. d) Will the location of the image move or stay the same? Suppose the arrow is moved 2 feet closer to the mirror. e) Will the location of the image move or stay the same? f) Will the size of the image increase, decrease, or remain the same? g) Will the angular size of the image increase, decrease, or remain the same?

Explanation / Answer

a) Location of the image will stay the same. It will depend only on the position of the image with respect to mirror.

b) Size will also not change, it will remain the same.

c) Angular size of the image will decrease as observer will move away from the mirror. Angular size will depend on the relative position of the observer with respect to object (Arrow here).

d) Location of the image will again stay the same.

e) Now the image of the arrow will move and it will be closer to the mirror.

f) Size of the image will remain the same.

g) Angular size will again decrease.
