A ray of light is incident normally on one of the faces of a prism of apex angle 30^@ and refractive index sqrt2 .Find the angle of deviation for the ray of light.

Three rays of light -red(R),green(G) and blue(B)-are incident on the face AB of a rigth-angled prism ABC as shown in Fig.3.27. The refractie indices of the material of the prism for red,green and blue wavelengths are 1.39,1.44 adn 1.47 respectively. Trace the path of the rays thruogh the prism.How will the situation change,if these rays were incident normally on one of the faces of an equilateral prism?

A narrow beam of light is incident normally on one face of a glass prism having refractive index 1.48 . Find the angle of prism if the ray makes a grazing emergence along the other face. Draw a diagram showing the path of rays.

Trace the path of these rays after passing through face 'ab'.

Calculate the angle of emergence (e) of ray of light incident normally on the face AC of a glass prism ABC of refractive index sqrt 3 . How will the angle of emergence change qualitatively if the ray of light emerges form the prism into a liquid of refractive index 1.3 instead of air?

The refrating angle of a prism is 40^@ and the refractive index of its material is given by mu=1.25 + b/(delta^2) When a ray of light is incident normally on the face AB of the prism,after refraction through the prism,the ray of light just grazes along the face AC as shown in Fig.3.20. . Find the critical angle for the material of the prism.
