Question

We always say that the refractive index of glass is 1.5. Again we know for different wavelength of lights the refractive index is different. So for which colour/wavelength of light refractive index of glass is 1.5?​

Answer 1

Refractive index is absolutely 1.5

Explanation:

Refractive index of a material depends on its surrounding medium but not on wavelength of light.

For materials refractive index is taken surrounding as vaccum or air but not light.
