If the light of a particular colour is passed through a prism, will it produce a spectrum after refraction?
Answer: Sending light rays of a particular colour through a prism does not form a spectrum. Because prisms do not create colour. When the light of many colours falls on a prism, the prism separates the colours. A light of a particular colour consists of only one colour. So after being refracted by the prism, the band of light of that colour will be created on the screen, and the spectrum will not be available.
