A beam of white light enters a transparent material. Wavelengths for which the index of refraction is n are refracted at angle .Wavelengths for which the index of refraction is n + , where , are refracted at angle . a). Show that the angular separation of the two wavelengths, in radians, is . b). A beam of white light is incident on a piece of glass at 30.0°. Deep violet light is refracted 0.28° more than deep red light. The index of refraction for deep red light is known to be 1.552. What is the index of refraction for deep violet light?

Given values

a). From Snell's law, we have

sin 1= n sin 2 and sin 1

=(n+n) sin (2+)

b) we use formula,

From previous formula ,we have to find value for
