Light refraction

1- What is light?

Light is a kind of energy

2- what is the light refraction??

Refraction is the change in direction of a wave, caused by the change in the wave's speed.

Refraction is seen most often when a wave passes from one medium to a different medium.

when a light wave travels through air and then passes through water, the wave will slow and change direction.


3- Experiment:

          What you need:

               Water

               Jar or glass

               A laser.


4- Refraction 

Refraction is the bending of light as it passes from one susbtance to another. Here, the light ray passes from air to water. The bending is caused by the differences in density between the two substances.
