heres ur answer

BRILLIANT QUESTION THOUGH

The refractive index for red light in glass is slightly different than for violet light. Violetlight slows down even more than red light, so it is refracted at a slightly greater angle. The refractive index of red light in glass is 1.513.

Answer 2

Answer:

The refractive index of glass is least for red light.

Explanation:

• Refractive Index: The refractive index of a medium is the ratio of the velocity of light through the air to the velocity of light through the medium.
• The refractive index is symbolized by 'n'. Velocity of light through air is indicated by 'c' and the velocity of light through the medium is 'v'. Then we can write, n = $\frac{c}{v}$.
• The refractive index of any medium depends on the wavelength of the light and the relation is inversely proportional.
• Among all the colors red color has maximum wavelength and violet color has minimum wavelength.
• Maximum wavelength means minimum refractive index. (as refractive index and wavelength are inversely proportional)
• That's why red color has least refractive index.
