Reflection from Curved Surface

In case of eflection from curved surface

Refraction From Curved Surface||Formula & Magnification||Principle Foci||Power OF a spherical Surface||Examples

Plane surface of a thin planoconvex lens reflects 50% of light, while the curved surface is completely transparent, if final image of O after refraction through lens coinsides with the image formed due to partial reflection from plane surface. if distance (in m) between O and lens is x then find x//4

A parallel beam of light of intensity I is incident on a glass plate. 25% of light is reflected in any reflection by upper surface and 50% of light is reflected by any reflection from lower surface. Rest is refracted The ratio of maximum to minimum intensity in interference region of reflected rays is

The wave reaching the receiving antenna will have maximum intensity if the direct wave & wave after reflection from earth's surface
