Question

Problem 26.92

A horizontal incident beam consisting of white light passes through an equilateral prism, like the one shown in the figure(Figure 1) .

Part A

What is the dispersion (?v??r) of the outgoing beam if the prism's index of refraction is nv = 1.505 for violet light and nr = 1.426 for red light?

Problem 26.92

A horizontal incident beam consisting of white light passes through an equilateral prism, like the one shown in the figure(Figure 1) .

Part A

What is the dispersion (?v??r) of the outgoing beam if the prism's index of refraction is nv = 1.505 for violet light and nr = 1.426 for red light?

Explanation / Answer

angular dispersion =(nv - nr)A =(1.505 -1.426)*600=4.740
