A real object is kept in air and refraction occurs at the convex boundry of a spherical glass surface. For the image to be real, the real object distance (n_(g)=3//2)

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 convex spherical refracting surfaces separates two media glass and air (mu_g=1.5). If the image is to be real, at what minimum distance u should the object be placed in air if R is the radius of curvature

A convex spherical refracting surfaces separates two media glass and air (mu_g=1.5). If the image is to be real, at what minimum distance u should the object be placed in air if R is the radius of curvature

Radius of curvature of a concave spherical surface separating air-glass medium is R. A point object is placed on the principal axis in the glass (m_(g) = 1.5) . For the image to be real seen by observer in air, distance of the object from P should be
