Light of two colours A and B pass through a prism. A deviates more than B from its path of incidence. Which colour has a higher speed in the prism?

Answered by sdevikrishna00855

Colour B deviates more than colour A. Thus, colour B has a higher speed.

sdevikrishna00855: Yes off course.. Please wait.

sdevikrishna00855: And thank you very much for selecting it in Brainlist

sdevikrishna00855: The wavelength of B is the largest, hence it has the greatest velocity while travelling through the medium.hence it passes without facing much deviation. Since A deviates more since it has least wavelength and have least velocity. The wavelength and frequency of a wave both are directly proportional to the velocity of the wave. £f=v, where £=Wavelength of the wave,f= frequency of the wave, v=velocity of the wave. From this equation we get that wavelength is directly proportional to velocity.

sdevikrishna00855: HOPE YOU GOT IT!

amruthaabi: Thank you

amruthaabi: But my exam was over by the time I saw this

sdevikrishna00855: Ohh.. I'm sry.. How was that exam

amruthaabi: It was fine

amruthaabi: Thankfully it didn’t have questions of this type

sdevikrishna00855: Ok!

B deviates more than A. Thus, B has a higher speed.

amruthaabi: Please give the reason too
