प्रश्न
Make two diagrams to explain refraction and dispersion.
उत्तर
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.
