1.3 Refraction

In the reference, the solid with the next highest index of refraction after diamond is zircon. If the diamond in the example were replaced with a piece of zircon, what would be the new angle of refraction?

Will light change direction toward or away from the perpendicular when it goes from air to water? Water to glass? Glass to air?

Unless otherwise specified, for problems 1 through 10, the indices of refraction of glass and water should be taken to be 1.50 and 1.333, respectively.

A light beam in air is incident on the surface of a pond, making an angle of $20 °$ with respect to the surface. What are the angles of reflection and refraction?

Unless otherwise specified, for problems 1 through 10, the indices of refraction of glass and water should be taken to be 1.50 and 1.333, respectively.

A pencil flashlight submerged in water sends a light beam toward the surface at an angle of incidence of $30 °$. What is the angle of refraction in air?

Unless otherwise specified, for problems 1 through 10, the indices of refraction of glass and water should be taken to be 1.50 and 1.333, respectively.

The path of a light beam in air goes from an angle of incidence of $35 °$ to an angle of refraction of $22 °$ when it enters a rectangular block of plastic. What is the index of refraction of the plastic?

Unless otherwise specified, for problems 1 through 10, the indices of refraction of glass and water should be taken to be 1.50 and 1.333, respectively.

(a) Using information in the preceding problem, find the height of the instructor’s head above the water, noting that you will first have to calculate the angle of incidence. (b) Find the apparent depth of the diver’s head below water as seen by th…
