Question

10 points help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Sunlight is slowed MOST when traveling through Question 21 options: A.water. B. a vacuum. C.the atmosphere. D.None of these, as light always travels at the same speed.

Answer 1

Sunlight is slowed most when traveling through water. The more optically dense medium slows it down, this is why it bends (refracts) as it enters.

Answer 2

The answer to this question would be: A. Water

The speed of light will be decreased when it moves in a media that has a higher index of refraction. In the atmosphere, the light is move inside air. When light moves inside water, it will be slower than when it moves in the atmosphere because water index of refraction is 1.33 times of air.
Pencil looks like bent when you put on water is an example of what happens by the difference of index of refraction.
