The equation of refraction at a spherical surface is `mu_2/v-mu_1/u=(mu_2-mu_1)/R`
Taking `R=oo`, show that this equation leads to the equation
`(Real depth)/(Apparent depth)=mu_2/mu_1` for fraction at a plane surface.

Is the formula "Real depth/Apparent depth = mu." valid if viewed from a position quite away from the normal ?

The correct expression for refraction at single convex spherical surface separating two media of refractiv eindices mu_(1) and mu_(2) ( mu_(2) gt mu_(1)) and radius of curvature R is ( u and v are object, image distane respectively )

When refraction occurs from denser to……….., then (mu_2)/(mu_1) = …………. .

What is the relation between the refractive indices mu,mu_(1) and mu_(2) if the behaviour of light rays is shown in Figure.

Path of ray of light passing through three liquids of refractive indices mu_1,mu_2,mu_3 is as shown in Fig. Which liquid has the smallest index of refraction ? .

The relation between refractive indices u, mu_(1),mu_(2) . if the behaviour of light ray is as shown in figure

Figure shows figure three transparent medi of refractive indices mu_1, mu_2 and mu_3 . A point object O is placed in the medium mu_2 . If the entire medium on the right of the spherical surface has refractive index mu_1 , the image forms at O. If this entire medium has refractive index mu_2 the image form at O''. In the situation shown

The reciprocalof ((mu_(2)-mu_(1))/(R)) gives the value of
