Light is incident upon air-water interface (n=1.33). Calculate
the Brewster and critical angles for both internal and external
reflections. In each case, distinguish between polarization modes.

Light from a strongly unpolarized light source is reflected at
the Brewster angle towards a water surface. The reflected light is
directed towards a polaroid filter and after the filter the
irradiance is measured. When the filter's transmission axis is
parallel to the E-field result vector, a maximum irradiance of 500
W / m² is measured.

1.a. Natural light propagating through air (index of refraction
n = 1) is incident on the surface of a transparent substance at an
angle of 60◦ with normal. At this angle, the reflected light is
seen to be completely polarized. What is the index of refraction of
the transparent substance? Draw a picture to show the orientation
of the electric field of the reflected light.

An oil film (n = 1.45) floating on the surface of water has
white light incident on it at normal angle of incidence (i.e.
perpendicular to the film). The film is 280 nm thick. For this
problem, you will need to know that the visible spectrum consists
of wavelengths of light from 400 to 700 nm.
