Relation between Focal Length and Radius of Curvature

a concave mir...

Question

a concave mirror has been so placed on a table that its axis remains vertical p and C are pole and centre of curvature respectively when a point light object is placed at C its real image is formed at C if now water is filled in the mirror what can we say about the position of image

Solution

Dear student

focal length of a mirror only depends on its radius, does not depend on medium in which it is placed

so there is no change in position of image due to immersion of mirror in water,

Q. An object is placed between a convex and a concave mirror. The pole of the convex mirror coincides with the centre of curvature of the concave mirror. Suppose an object is placed at the focus of the concave mirror. What will be the nature of the image formed by the concave mirror of the image formed by the convex mirror?
