For a spherical surface,when refraction takes place from a rarer medium (mu_1) to a denser medium (mu_2) , we write -(mu_1)/u + (mu_2)/v = ( mu_2-mu_1)/R where the symbols have their usual meanings. Now suppose that the object is placed in the denser to the rarer medium . Then, rewrite the above equation.

A ray is incident at an angle of incidence i on one surface of a prism of small angle A and emerges normally from the opposite surface. If the refractive index of the material of the prism is mu , the angle of incidence i is nearly equal to

For a ray of light travelling from a denser medium of refractive index mu_1 to a rarer medium of refractive index mu_2 ,prove that (mu_2)/(mu_1) = sin C , where C is the critical angle of incidence for the media.

A prism of refractive index mu_1 and another prism of refractive index mu_2 are struck together without a gap as shown in Fig.3.17. . The ngles of the prisms are shown . mu_1 and mu_2 depend on delta ,the wavelength of light according to mu_1=1.20 +(10.8 xx 10^4)/(delta^2) and mu_2 = 1.45 + (1.8 xx 10^4)/(delta^2) , where delta is in nm. Calculate the wavelength delta_0 for which rays incident at any angle on the interface BC pass through without bending at that interrface.

A convex lens made of a material of refractive index mu_1 , is kept in a medium of refractive index mu_2 , Parallel rays of light are incident on the lens. Complete the pathof rays of light emerging from the convex lens if mu_1 = mu_2 .

A convex lens made of a material of refractive index mu_1 is kept ih a medium of refractive index mu_2 , Parallel rays of light are incident on the lens. Complete the path of rays of light emerging fromthe convex lens if mu_1 > mu_2 .

A double convex lens made from a material of refractive index mu_1 is immersed in a liquid of refactive index mu_2 where mu_2 > mu_1 . What change, if any, would occur in the nature of the lens?

Starting new cartesian sign conventions, derive the relation. -frac(mu_1)(u) + frac(mu_2)(v) = frac(mu_2-mu_1)(R) , when refraction occurs from rarer to denser medium at convex spherical refracting surface (mu_1 lt mu_2) . Where u, v and R are object distance, image distance and radius of curvature of spherical surface respectively.
