Answer:
The light bends away from the normal
Explanation:
We can solve the problem by using Snell's law:

where:
is the index of refraction of the first medium
is the index of refraction of the second medium
is the angle of incidence (angle between the incoming ray and the normal to the interface)
is the angle of refraction (angle between the outcoming ray and the normal to the interface)
We can rearrange the equation as

In this problem, light travels from an optically denser medium to an optically rarer medium, so

Therefore, the term
is greater than 1, so

which means that the angle of refraction is greater than the angle of incidence, and so the light will bend away from the normal.

Answer:
t = 94.91 nm
Explanation:
given,
wavelength of the light = 522 nm
refractive index of the material = 1.375
we know the equation
c = ν λ
where ν is the frequency of the wave
c is the speed of light


ν = 5.75 x 10¹⁴ Hz
the thickness of the coating will be calculated using


t = 94.91 nm
the thickness of the coating will be equal to t = 94.91 nm
Set this up as a proportion.
.002 m^3/20 degrees = x/50 degrees
solve for x
x = .005 m^3
