Chapter 16, Problem 1CQ
Light can pass easily through water and through air, but light will reflect from the surface of a lake. What does this tell you about the
Expert Solution & Answer
To determine
To explain: Speed of light in air and water.
Explanation of Solution
As light passes from air to water, it changes from one medium to another. In terms of refractive index, water is denser than air.
Hence, the wave speed of light decreases in water. Therefore, some light waves undergo refraction, while some of them reflect back from the plane of water.
Conclusion:
Hence, the speed of light in air and water is described.

- Unpolarized light in vacuum is incident onto a sheet of glass with index of refraction n. The reflected and refracted rays are perpendicular to each other. Find the angle of incidence.

On June 30, 1908, a meteor burned up and exploded in the atmosphere above the Tunguska River valley in Siberia. It knocked down trees over thousands of square kilometers and started a forest fire, but produced no crater and apparently caused no human casualties. A witness sitting on his doorstep outside the zone of falling trees recalled events in the following sequence. He saw a moving light in the sky, brighter than the Sun and descending at a low angle to the horizon. He felt his face become warm. He felt the ground shake. An invisible agent picked him up and immediately dropped him about a meter from where he had been seated. He heard a very loud protracted rumbling. Suggest an explanation for these observations and for the order in which they happened.arrow_forwardA ray of light enters a liquid from air.
