This week in Science, we have considered the question ‘What causes rainbows?’ We found out that rainbows are caused when light travels from one state of matter to another causing the colours of light to separate! We observed this in class too in which we used a prism and torch to make a rainbow. We also observed how a pencil looks distorted in water due to the light travelling at different speeds in different states of matter!
