Horizontal rays of red light (λ = 660 nm, in vacuum) and violet light (λ = 410 nm, in vacuum) are incident on the flint-glass prism shown in the drawing. The indices of refraction for the red and violet light are nred = 1.662 and nviolet = 1.698. The prism is surrounded by air. What is the angle of refraction for (a) red ray, (b) violet ray as it emerges from the prism?
In problem to find the angle of refractions emerging from prism we use snell's law
This equation will be modified a little bit for red ray and violet ray when calculating angle of refractions emerging from prism
angle of refraction emerges from prism
For red ray,
For violet ray,
