Q1: Light is incident from air (n= 1)
to glass (n = 1.51). The light has a
wavelength of 541 nm in air
a) If the angle of incidence is 37", what
are the angles of reflection and of
refraction?
%3D
b) What is the wavelength of the light in
the glass?
Q2: Light in a material with an index of
refraction of 1.57 is refracted into air, at
an angle of refraction of 56".
(a) What is the angle of incidence?
(b) What is the speed of light in
material?
Q3 : A beam of light passes through
a block of glass 10.0 cm thick, then
through water for a distance of 30.5
cm, and finally through another block
of glass 5.0 cm thick. If the refractive
index of both pieces of glass is 1.5250
and of water is 1.3330, find the total
optical path.
