Question

1. Out of red and blue lights, for which is the refractive index of glass greater?​

Answer 1

Explanation:

So, as you have stated, red light has a lower index of refraction than blue light since it also has a shorter wavelength, so lower index of refraction corresponds to higher speed in a material. n2=1.51 for red light and θ2=13.09 degrees, n2=1.53 for blue light, and θ2=12.91 degrees

Answer 2

Answer:

The refractive index of glass is 1.520 for red light and 1.525 for blue light. -   The refractive index of glass is 1.520 for red light and 1.525 for blue light. The refractive index of glass is 1.520 for red light and 1.525 for blue light.

So, as you have stated, red light has a lower index of refraction than blue light since it also has a shorter wavelength, so lower index of refraction corresponds to higher speed in a material  The index of refraction is always greater than or equal to 1, because , the speed of light in vacuum, is always greater than the speed in a material. So, as you have stated, red light has a lower index of refraction than blue light since it also has a shorter wavelength, so lower index of refraction corresponds to higher speed in a material.
