Question

State whether true or false :

When light falls on a prism the result can be magnification.

• A. True
• B. False

Answer 1

The correct option is B False

When light falls on the glass prism, refraction takes place. Since the wavelength of different components of light is different and the frequency is constant, each component gets deviated by a different angle due to the difference in velocity in the glass medium. The red color having the maximum wavelength deviates the least and forms the upper part of the spectrum whereas violet having the least wavelength deviates the most.
