Question
Make two diagrams to explain refraction and dispersion.
Advertisements
Solution
When we see a pool of water. The pool appears less deep as it is. This is due to the refraction of light.
When white light is allowed to pass through the glass prism. It splits into seven colour this is called dispersion of light.
