Explain, what happens when a beam of sunlight is passed through a glass prism.
Sunlight is the combination of seven components. When sunlight is allowed to pass through the glass prism it blends and gets split into seven colours. All the seven colour has different wavelength and while entering through a prism it bends (due to refraction) and angle of bending is different for all the colour. And while coming out from the prism light again get bend and we can see the entire different colour. This is also called Dispersion means spreading of white light into its full spectrum.

A student makes a device P by using three long and narrow strips of plane mirrors inclined at 60° to one another which enables him to see beautiful patterns made by pieces of coloured glass bangles. On the other hand, another student makes a device Q by using two plane mirrors arranged parallel to each other which helps him to see a football match clearly even when some very tall persons are sitting in front of him in the ground. What are P and Q?Lakhmir Singh & Manjit Kaur - Science
