Which of the following are concave mirrors and which convex mirrors ?

Characteristics of Focus of a Concave Mirror and a Convex Mirror Convex Mirror Concave Mirror The focus lies behind the mirror. The focus is in front of the mirror. The focus is virtual as the...

(a) Our image will be diminished, virtual and erect. This is because when the object lies anywhere between the pole and inifinity, the concave mirror forms a diminished, virtual and...

(a) Myopia  (b) Hypermetropia

Convex lens: (i) It converge the incident rays towards the principal axis. (ii) It has a real focus. Concave lens: (i) It diverges the incident rays away from the principal axis. It has a...

Concave lens will show the divergent action on a light beam.

A lens is called an equiconvex or equiconcave when radii of curvature of the two surfaces of lens are equal.

It is a concave.

The two applications of a convex lens are:- (i) It is used as an objective lens in a telescope, camera, slide projector, etc. (ii) With its short focal length it is also...

(i) On seeing a distant object through the lens, if its inverted image is seen, then the lens is convex, and if the upright image is seen, then the lens...

(i) Image is of same size in plane mirror. (ii) Image is enlarged in concave mirror. (iii) Image is diminished in convex mirror. (iv) Image in all the three is virtual.
