Question

The ratio of the refractive index of red light to blue light in glass is
a) <1
b) > 1
c) = 1
[
d) can be >1 or <
​

Answer 1

Answer:

I have got it as 1.0

Explanation:

Since both the red and blue light are in a vacuum there is no refraction. Light both red and blue travel at the same speed through the vacuum. So the ratio of their speed is 1.0. Refractive index is inversely proportional to square of wavelength of light
