Bella and Asante now work a problem to determine whether they understand total internal reflection. A thin film of water sits on top of a flat piece of glass. Note that n, 'water = 1.333 and n 'glass = 1.56. For total internal reflection, does Asante say the light starts in the glass or in the water? "In the water, because the water has a higher index of refraction" "In the glass, because the glass has a lower index of refraction" "In the glass, because the glass has a higher index of refraction" "In the water, because the water has a lower index of refraction" Asante is correct. Total internal reflection can occur only when light travels from a region of higher to lower index of refraction. What is the critical angle for which total internal reflection will occur?

Concept explainers

Refraction of Light

Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.

Angle of Refraction

Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic radiation whereas part of it is perceived by humans. Visible spectrum defined by humans lies in a range of 400 to 700 nm wavelengths.

Index of Refraction of Diamond

Diamond, the world’s hardest naturally occurring material and mineral known, is a solid form of the element carbon. The atoms are arranged in a crystal structure called diamond cubic. They exist in a huge variety of colours. Also, they are one of the best conductors of heat and have a very high melting point.

Question

Bella and Asante now work a problem to determine whether they understand total internal reflection.
A thin film of water sits on top of a flat piece of glass. Note that n
water
= 1.333 and n
glass
= 1.56.
For total internal reflection, does Asante say the light starts in the glass or in the water?
"In the water, because the water has a higher index of refraction"
"In the glass, because the glass has a lower index of refraction"
"In the glass, because the glass has a higher index of refraction"
"In the water, because the water has a lower index of refraction"
Asante is correct. Total internal reflection can occur only when light travels from a region of higher to lower index of
refraction.
What is the critical angle for which total internal reflection will occur?

(a) An opaque cylindrical tank with an open top has a diameter of 2.60 m and is completely filled with water. When the afternoon sun reaches an angle of 31.5° above the horizon, sunlight ceases to illuminate any part of the bottom of the tank. How deep is the tank (in m)? 4 Determine how the depth of the tank is related to the angle of refraction for the geometry described in the question. Drawing a diagram may be helpful.

On winter solstice in Seattle, the sun reaches a maximum altitude of 19° above the horizon. What would the depth of the tank have to be (in m) for the sun not to illuminate the bottom of the tank on that day? m
Snell's Law and the Law of Reflection explain how light is redirected when it encounters a surface between two media. In the extreme, light may only reflect at a boundary, and go back into the medium it was in. More often, some of it reflects and some goes through. If the boundary is plane and flat, then these laws are easy to interpret. When the boundary is curved, they describe happens at every point on the surface. One of the class types of glass is called "crown" glass, which has an index of refraction for visible light of 1.52 and is usually free of significant impurities. It was one of the first glasses discovered, and windows are made from it. Another glass is called "flint" glass, and it has lead oxide added, which makes it heavier, more "dispersive" and colorful, and increases its index of refraction to 1.62. For the flint glass, the refracted ray goes through the glass to the other side. If the glass is a parallel slab, what happens when the ray reaches the…
