Spherical surface refraction

Spherical Surface||Refraction and thin Lens

A small point object is placed at O at a distance of 0.60 metre in air from a convex spherical surface of refractive index 1.5 .If the radius of the curvature is 25cm then what is the position of the image on the principal axis.

Plane surface refraction

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.

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

A spherical surface of radius 30 cm separates two transparent media A and B with refractive indices 1'33 and 1.48 respectively. The medium A is on the convex side of the surface. Where should a point object be placed in medium A so that the paraxial rays become parallel after refraction at the surface ?

A spherical surface of radius 30cm separates two transparent media A and B with refractive indiecs 1.33 and 1.48 , respectively. The medium A is on the convex side of the surface. Where should a point object the placed in medium A so that the paraxial rays become parallel after refraction at the surface?

A concave spherical surface of radius of curvature 100 cm separates two media of refractive indices 1.50 and (4)/(3) . An object is kept in the first medium at a distance of 30 cm from the surface. Calculate the position of the image.
