Question

important question related with higgen rule 12 optics

Answer 1

Hi there ..!!

most of the important questions from hygen's principle will be about the frequency , velocity and wavelength .

key points are :

1 )refractive index of the medium is inversely proportional to wavelength .

2) the velocity and wavelength varies but frequency remains constant .

most of the questions from hygen's principle will be based on theory

Answer 2

the velocity varies but the frequency remain constant
