A monochromatic ray of light enters a flat piece of glass (index
of refraction = n) from air (index of refraction n = 1). The ray
passes through the glass and re-enters the air through the bottom
surface of the glass sheet. The angle it makes with the normal when
it has re-entered the air is
a.
the same as the angle it made with the normal when it was
originally in air.
b.
the same as the angle it...

An aquarium filled with water (n = 1.33) has flat glass sides
whose index of refraction is 1.51. A beam of light from outside the
aquarium strikes the glass at a 43.5∘ angle to the perpendicular

glass? Express your answer using three significant figures. θ2
=
Part B What is the angle of this light ray when it enters the
water? Express your answer...

A block of crown glass of refractive index 1.52, is immersed in
water of refractive index 1.33, as in the figure shown below. A
light ray is incident on the top face at an angle of
θ1 = 42.2° with the normal and exits the block
at point P. (Assume that x = 3.63 cm.)
A block is immersed in water. A ray starts in the water at the
top of the image and moves down and to the right...

A triangular glass prism with apex angle of 60.0° has an index
of refraction n=1.50. What is the smallest angle of incidence for
which a light ray can emerge from the other side if the prism is
surrounded by (i) air (n=1.00), (ii) water (n=1.33)?

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...
