Question

What is the relation between wavelength of light ray
incident on a
glass and the refractive index of glass?​

Answer 1

Explanation:

The refractive index can be seen as the factor by which the speed and the wavelength of the radiation are reduced with respect to their vacuum values: the speed of light in a medium is v = c/n, and similarly the wavelength in that medium is λ = λ0/n, where λ0 is the wavelength of that light in vacuum.

Answer 2

Answer:

The Wavelength is represented by the symbol λ.

Any wave's Wavelength Formula is given by,

λ=v/f

The wavelength is measured in metres, the velocity is measured in metres per second, and the frequency is measured in hertz.

Now, if we look at both the formulas, i.e., the formula of the refractive index of a material and the formula of the wavelength, we can write

λ=c/nf because [n=c/v]

Therefore, we can conclude that the wavelength is inversely proportional to the refractive index of the material in which the wave is travelling.
