Derive the equation relating u,v and R in case of refraction i a medum of refactive index `mu_1` from a medium of refractive index `mu_2` .State te assumption made in you deriation.

A concave lens made of a material of refractive index mu_g is immersed in a medium of refractive index mu_l , equal to and

Obtain lens makers formula using the expression (mu_1)/u + (mu_2)/v = (mu_2-mu_1)/R Here the ray of light propagating from a rare r medium of rerfracitve index (mu_1) to a dneser medium of refractive indes (mu_2) is incident on the convex side of spherical refracting surface of radius of curvature R.

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.

Derive the relation between refractive index of the medium and critical angle.

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?

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 .
