Question

If ngw is greater than nwg1 , then the speed of light un water will be _______ with respect to glass.​

Answer 1

Answer:

Explanation:

225,000 kilometers per second

Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water (refractive index of 1.3; see Figure 2) and 200,000 kilometers per second in glass (refractive index of 1.5).
