Question

rays of red and blue light are incident on a given small angled prism.which will have larger value of angle of minimum deviation and why?

Answer 1

Blue will have the larger value of angle of minimum deviation because it has a shorter wavelength and hence is deviated by even small particles.

Answer 2

Blue light deviates the most as greater the refractive index of a particular colour in a given medium more is the deviation of the corresponding ray of that particular colour
