What is the speed of light in Ethanol?

What is the speed of light in Diamond?

Calculate the index of refraction for a medium in which the speed of light is

2 × 10^8 m/s

The speed of light is

2 × 10^8 m/s. Identify the most likely substance:

Components of some computers communicate with each other through optical fibers having an index of refraction n = 1.5. What time in nanoseconds is required for a signal to travel 0.200 m through such a fiber?

Suppose you have an unknown clear substance immersed in water, and you wish to identify it by finding its index of refraction. You arrange to have a beam of light enter it at an angle of 45.0°, and you observe the angle of refraction to be 40.3°.
