Question

1. For which colour violet or green-does glass have a larger refractive index​

Answer 1

Answer:

voilet

The index of refraction varies with frequency, it doesn't change as light travels from one medium to another, As violet colour has the shortest wavelength and so the refractive index is maximum for it.

Answer 2

Answer:

Which colour, violet or green, has a larger refractive index?

Refractive index describes the medium that light travels through. The color refers to the frequency of the light itself. These are two different things. However, in general violet light will usually experience a higher refractive index than green. Be cautious with this comparison. The properties of materials can get quite crazy in the UV spectrum.

If you want to learn more, look under “Material Properties” at the following link. There are a few resources for you to look up refractive index for various materials as a function of wavelength or frequency.
