In this lesson, we will learn how to calculate the deflection of light rays at interfaces of materials within which light travels at different speeds.
Sample Question Videos
The refractive index of crown glass is 1.52. What is the speed of light in crown glass?
Components of some computers communicate with each other through optical fibers having a refractive index of 1.55. What time in nanoseconds is required for a signal to travel 0.200 m through such a fiber?
A light beam in air is incident on the surface of a pond with a refractive index of 1.333, making an angle of 20° with respect to the surface of the pond.
What is the angle of reflection?
What is the angle of refraction?
