Show that for refraction at a concave spherical surface (separating glass-air medium), the distance of the object should be greater than three times the radius of curvature of the refracting surface for the image to be real.

Show that for refraction at a concave spherical surface (separating glass-air medium), the distance of the object should be greater than three times the radius of curvature of the refracting surface for the image to be real.

A concave spherical surface of radius of curvature R = 20 cm separates two media A and B having refractive indices mu_(A) =(4)/(3) and mu_(B) =(3)/(2) respectively. A point object is placed on the principal axis. Find the distance of the object from the surface so that its image is virtual when (a) the object is in medium A. (b) the object is in medium B.

Refraction takes place at a concave spherical boundary separating glass air medium. For the image to be real, the object distance (mu_(g)=3//2)

If the object is placed on the principal axis at a distance of 10 cm in front of a concave mirror with curvature is 8 cm, what is the distance of the image ?
