Define the following terms related to curved mirrors :
(A) Focus (b) Principal axis ( c ) Centre of curvature (d) Radius of curvature

Define: Radius of curvature and centre of curvature

Define the following : (a) Principal axis, (b) Focal ength, ( c ) Pole (d) Centre of curvature.

Draw ray diagrams showing the image formation by a concave mirror when an object is placed (a) between pole and focus of the mirror , (b) between focus and centre of curvature of the mirror (c) at centre of curvature of the mirror , (d) a little beyond centre of curvature of the mirror (e) at infinity

When the object is at centre of curvature of a concave mirror, its image is formed at the centre of curvature. ____

Geometric centre of a spherical mirror is called its centre of curvature. _____

Define the principal focus of a concave mirror.

Discuss the properties of image formed by shown mirror of a real object place beyond centre of curvature

(a) If the image formed by a mirror for all positions of the object placed in front of it is always diminished, erect and virtual, state the type of the mirror and also draw a ray diagram to justify your answer. Write one use such mirrors are put to and why? (b) Define the radius of curvature of spherical mirrors. Find the nature and focal length of a spherical mirror whose radius of curvature is +24 cm.

If the focal lenght of a convex mirror is 12 cm, what would be its radius of curvature?

Define the terms pole, principal axis and centre of curvature with reference to a spherical mirror.
