The polarizing angle of incidence of gemstone, ip = 64.50
Refractive index of diamond, n = 2.419
(a)
Using Brewster’s law, tan ip = n
tan 65.5 = n
refractive index of gemstone, n = 2.096
the given gemstone is not diamond as the refractive index of gemstone is n = 2.096 while the refractive index of diamond is, n = 2.419
(b)
Refractive index of water, n = 1.333
Using Brewster’s law, tan ip = n = 1.333
The polarizing angle of incidence, ip = tan-1 1.333 = 53.10
The polarizing angle of incidence for water, ip = 53.10

Project (2) Read the manual When unpolarized light is incident on the surface of (say) glass at the Brewster angle, the reflected light is polarized with its polarization parallel to the surface of the glass. The Brewster angle is given by Tan(O) = n where n is the refractive index of glass. The material need not be glass; it could be plastic, water etc. (any smooth transparent material is fine). Exercise: (1) The Brewster angle in the experiment is found...

water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.
These effects on light propagation occur because light travels at
different speeds depending on the medium. The index of refraction
of a material, denoted by n, gives an indication of the speed of...

Answer those Question please
QUESTION 6 A ray of light passes through a layer of oil which has a refractive index of 1,38 and strikes the boundary with a layer of water at an angle of 18 7 degrees to the normal. If the water has a refractive index of 1.33, what is the angle in degrees of the ray in the water relative to the normal? (State answer with 1 digit right of decimal. Do not include unit.)
