A ray of light in air with a wavelength of 400 nm is incident on a liquid with an index of refraction of 1.4. The ray of light makes an angle of 45 degrees with the normal when it enters the liquid from the air.
a) Determine the speed of the light in the liquid.
b) What is the wavelength of the ray of light in the liquid?
c) Find the angle of the refracted ray.
d) Suppose that you want a totally internal reflected ray, should the ray go from the air to the liquid or vice versa? Determine the maximum angle for total internal reflection in this medium?
