Question

Monochromatic light of yellow colour is incident at an equilateral prism at an incidence angle of 48 and suffers minimum deviation. What is the angle of emergence? Calculate the angle of minimum deviation. If the angle of incidence is increased, will angle df deviation increase or decrease?

Answer 1

Refractive index is inversely proportional to the wavelength of the light. As red has a higher wavelength than violet light therefore it has a ...
