Refractive index varies with wavelength
WebThe index of refraction is greater for the denser medium than the rarer because the speed and in proportionate the wavelength of the wave is reduced while traveling through the denser medium. The refractive index of the medium is given as the velocities of the wave propagating from two different mediums. WebVariation in wavelength while propagating from two different mediums. The velocity of the wave in the rarer medium is more and hence the wavelength of the wave is increased. On …

WebRefractive Index and the Speed of Light cnk kn /( ) ( / )/ Note: often people don’t write the subscript 0 on c, even when they mean c 0. The speed of light is /k.Since k becomes nk in a medium, where c 0 is the speed of light in vacuum. nc c 0 / The refractive index, n, of a medium is thus the ratio of the speed of light in vacuum to the speed of light in the medium. WebMay 29, 2024 · The refractive index varies with wavelength linearly because different wavelengths interfere to different extents with the atoms of the medium. It is important to use monochromatic light to prevent dispersion of light into different colours. The chosen wavelength should not be absorbed by the medium.
