Answer:
Therefore, when a light ray traveling through air enters water or glass it slows down, refracts, and bends toward the normal line. ... For example, when light goes from glass or water to air, it speeds up. Refraction changes how objects look.
Explanation:
The light slows down when it passes from the less dense air into the denser glass or water. This slowing down of the ray of light also causes the ray of light to change direction. It is the change in the speed of the light that causes refraction.
How light and water affects the speed of the light?
- Light is slowed down in transparent media such as air, water and glass. The ratio by which it is slowed is called the refractive index of the medium and is always greater than one.
- Because of the physical differences in the makeup of the materials light actually travels slower through water and glass. Speed of light in a vacuum and air = 300 million m/s or 273,400 mph. Speed of light in water = 226 million m/s or 205,600 mph. Speed of light in glass = 200 million m/s or 182,300 mph.
