| [1] |  | Two people stand d= m away from a large plane mirror. They are spaced x= m apart. At what
angle does one of them have to shine the flashlight on the mirror so that the reflected beam shines on the other person?
|
| [2] |  | A coin is at the bottom of a swimming pool filled with liquid d= m deep. The liquid has an index of
refraction of nL= none (water has nL=1.3). How deep does the coin appear to be to someone looking at it
from the air above the water?
|
| [3] | A beam of light traveling in water strikes the surface of a transparent object at an angle of
\theta1= o . If the angle of refraction in the material is \theta2= o , what
is the index of refraction of the material.
|
| [4] | Light passes from medium A to medium B at an angle of incidence of \theta1= o . The index of
refraction of A is " " times that of B.
