Answer #1

A ray of light is traveling in glass and strikes a glass/liquid
interface. The angle of incidence is 58.0°, and the index of
refraction of glass is n = 1.50.

the direction of the light entering the liquid is not changed?
(b) What is the largest index of refraction that the liquid can
have, so that none of the light is transmitted into the liquid and
all...

E. B & C
F. A & D

a beam of light travels from air into a sheet of glass having
refractive index n.
a if we increase n, the angle of incidence, decreases
b if we double the angle of incidence, the angle of reflection
also doubles
c the angle of refraction will be greater than the angle of
incidence \
d if the angle of incidence is large enough, the light will be
totally reflected back into the air
e if we increase the angle of...

A ray of light traveling through air strikes a piece of diamond
at an angle of incidence equal to 55.5 degrees.
Calculate the angular separation in degrees between the
red light and the violet light in the refracted ray, given
that:
The index of refraction of violet light ( Lamdaviolet = 400nm)
in diamond is 2.46.
The index of refraction of red light ( Lamdared = 700nm) in
diamond is 2.41.
Enter the numeric value in degrees.

The drawing shows a ray of light traveling through three
materials whose surfaces are parallel to each other. The refracted
rays (but not the reflected rays) are shown as the light passes
through each material. A ray of light strikes the a–b interface at
a 50.0? angle of incidence. The index of refraction of material a
is na = 1.20. The angles of refraction in materials b and c are,
respectively, 42.6? and 58.7?. Find the indices of refraction in...
