A ray of light incident at `49^@` on the face of an equilateral prism passes symmetrically.Calculate thr efractive index of the material of the prism.

At what angle ,a ray of light will incident on one face of an equilateral prism,so that the emerget ray may graze the second surface of the prism(=1.5)?

Two monochromatic rays of light are incident normally on the face AB of an isosceles right-angled prism ABC.The refractive indices of the glass prism for the two rays 1 and 2 are respectively 1.35 and 1.45[Fig.2.76]Trace the path of these rays after entering through the prism .

A ray of light is incident at an angle of 60^@ on the first face of a prism of an angle 30^@ .The ray emergingn out of the prism makes an angle of 30^@ with the incident ray as shown in Fig.3.13. . calculate the refractive index of the material of the prism.

A ray OP of monochromatic light is incident on the face AB of prism ABCD mear vertex B at an incident angle of 60^@ (see figure). If the refractive index of the material of the prism is sqrt3, which of the following is (are) are correct? .

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 prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. The angle of minimum deviation is measured to be 40^@ . What is the refractive index of the material of the prism? The refracting angle of the prism is 60^@ . If the prism is placed in water (refractive index 1.33), predict the new angle of minimum deviation of a parallel beam of light.

A ray of light incident at an angle theta on a refracting face of a prism emerges from the other face normally. If the angle of the prism in 5^@ and the prism is made of a material of refractive index 1.5, the angle of incidence is:

A ray of light incident on an equilateral glass prism shows minimum deviation of 30^@ .Calculate speed of light through the glass prism.

At what angle should a ray of light be incident on the face of a prism of refracting angle 60^@ so that it just suffers total internal reflection at the other face? The refractive index of the material of the prism is 1.524.

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.
