Describe how light will reflect in the following
situations. State your answer in your own words.
Monday, April 28:
1. A light ray approaches a mirror, making an
angle of 20 degrees with the mirror surface. What is the
angle of reflection? _______ Explain your answer.
2. An object is placed 50 cm from a plane mirror. How
far is the image from the object? _______ Explain your
1. A microscopic view of a sheet of paper is
shown in the diagram at the right. Would you expect this
sheet of paper to cause light to undergo specular or
diffuse reflection? ____________ Explain.
2. What do you suppose would be an easier surface to
read - from pages of a book which are rough or from pages
which are smooth and glossy? _________________________
Explain your answer.

A 6-foot tall man is viewing himself in front of
a plane mirror. How much of the mirror does he need to
view his image? Does the amount depend upon his distance
from the mirror? Explain your answer.
Thursday, May 1:
Rose Inhatt stands 0.9 m in front of a dresser
mirror (labeled M2) with her hat on. She holds
a hand mirror (labeled M1) a distance of 0.6 m
behind her in an effort to view the image of a flower on
the back of her hat. By looking in M2, she is
able to view multiple images - primary, secondary,
tertiary, etc. Determine the distances (relative to
mirror M2) of the nearest three images which
could be seen in M2.

The two diagrams below show a concave mirror,
principal axis and arrow object. The focal point
and center of curvature are marked (but not labeled). For
each situation, draw a ray diagram and determine the
image location. Based on your ray construction, indicate
