# A hydrogen discharge lamp emits light with two prominent wavelengths: (red) and (blue). The light entersa flint-glass prism perpendicular to one face and then refractsthrough the hypotenuse back into the air. The angle betweenthese two faces is .a. Use Figure to estimate to the index of refractionof flint glass at these two wavelengths.b. What is the angle (in degrees) between the red and blue lightas it leaves the prism?

(a) The index of refraction of flint glass at these two wavelengths are and

(b) The angle between the red and blue light as it leaves the prism .

See the step by step solution

## part (a) step 1: Given Information

We need to estimate the index of refraction of flint glass at the two wavelengths.

## part (a) step 2: Simply

.Here is the wavelength and is refractive index.

## part (b) step 1: Given Information

We need to find angle between the red and blue light.

## part (b) step 2: Calculation

RED: BLUE:

.

Here is the refractive index and refraction angle.
