Refraction Example Problems
- A double-glazed window consists of two panes of glass separated
by an air space for
better insulation.
- (A) Assuming that the glass has an index of refraction of 1.5,
find
the angle at which a ray
of sunlight enters a room if it arrives at the window at an angle of
incidence of 700.
- (B) The window leaks, and the space between the panes becomes
filled with water. What
is the angle at which the ray enters the room now ?
- A glass paperweight in the form of a 60 mm cube is placed on a
letter. How far
underneath the top of the cube does the letter appear if the index of
refraction of the glass
is 1.5 ?
