for which colour of white light the refractive index of a transparent medium is most and least.Give reason for your answer |

Answer» ! HERE IS THE ANSWER......Red light has the MAXIMUM wavelength λ and frequency f of light doesn't change in any medium. Thus, red light travels fastest through a medium since v=fλRed light has the maximum wavelength λ and frequency f of light doesn't change in any medium. Thus, red light travels fastest through a medium since v=fλAccording to SNELL's law nv is constant for all the constituents of a SINGLE wave passing through a particular medium, here the seven wavelengths of white light. Since velocity v of red light through a medium is maximum, refractive index N for red light will be least.HOPE IT HELPS YOU.. |
