Oil is a less dense than liquid meaning it floats on top with an index of refraction of 1.15. Oil (thickness = 4 cm) lays on water on a windless day.
1) If a ray of light that has an angle of incidence of 45° as it enters the oil from the air above ,what would the angle of refraction in the water be?
2)How much time passes as the light travels through the oil layer
Homework Answers
Concept: we use Snell’s law to find the angle of refraction as shown below and we find the speed of light in oil to find the time taken to cross oil

A layer of olive oil (n = 1.45) floats on top of the surface of some water (n = 1.33). A ray of light hits the olive oil from air with an angle of incidence of 45 ∘∘. At what angle does the light emerge into the olive oil? A ray of light hits the olive oil from air with an angle of incidence of 45 ∘∘. At what angle does the light emerge into the water?

Canola oil is less dense than water, so it floats on water, but its index of refraction is 1.47, higher than that of water. When you are adding oil and water to a bottle to make salad dressing, you notice a silvery reflection of light from the boundary between the oil and water. What is the critical angle for light going from the oil into the water?
