Question

in an experiment of finding the refractive index of glass , if blue light is replaced by the red light , how will the refractive index of glass change ? give reason in support of your answer.



krish pls reply here

Answer 1

The refractive index will increase because red deviates the least and blue deviates much more than red..So in order to replace blue light by red..it has to deviate at a greater extent thus the converging power will have to be increased and so the refractive index
