REFRACTION OF LIGHT

 REFRACTION OF LIGHT

1. Light rays usually travel in straigh lines.

 2. When light travels or passes from one material to another of different density, light rays change direction and continue on a new straigh path.

 3. This phenomenon is called refraction.

Now, I will explain in a video this phenomenon.

First experiment

The mediums are: air and water. 

Second experiment

Light rays go through air, glass of water and go back to the glass, air and finally we see the arrows in opposite direction.
