|||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?|
|||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?
|||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.|
|||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.
