A hydrogen discharge lamp emits light with two prominent wavelengths: (red) and (blue). The light enters

a flint-glass prism perpendicular to one face and then refracts

through the hypotenuse back into the air. The angle between

these two faces is .

a. Use Figure to estimate to the index of refraction

of flint glass at these two wavelengths.

b. What is the angle (in degrees) between the red and blue light

as 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 .

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

.Here is the wavelength and is refractive index.

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

RED: BLUE:

.

Here is the refractive index and refraction angle.
