Question

As a demonstration of the refraction of light, she then shows the class an image of how the path of light changes when traveling from air through water compared with light traveling only through air.
Laser pointer beaming ray of red light in straight solid line to bottom of aquarium. At the point where it meets water a dashed line branches off until it shines a spot at the bottom of the aquarium closer to the center.

Using the image, explain how the path of light in air only compares with the path of light traveling from air through water.

Answer 1

Answer:

When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction. When light enters a more dense substance it 'bends' more towards the normal line.
