Explanation: light slows down when passing through the glass. Each color slows down a different amount making light bend
Since it wasn't enough info here, When light passes through lenses and through a set of prism then refraction will take place as the light is traveling from a rarer medium (air) to the denser medium (prism or lens). It is because of the change in the speed of the light.
We need a respiratory system to live because it is made up of organs that allow us to breathe. When we breathe, we deliver oxygen to the cells in our body to get energy from our food. This helps us live.
