2.Draw the Image formation by a convex mirror for different positions of the object
a. At infinity
b. Beyond C
Answers
Explanation:
Convex mirrors always form virtual images. This is because the focal point and the centre of curvature of the convex mirror are imaginary points and that cannot be reached. So the image is formed inside the mirror and cannot be projected on a screen. The image formed look smaller than the object from a distance but it gets larger as the object is brought closer to the mirror.

Some Important Terms
1. Pole: It is the centre of the reflecting surface of a spherical mirror. It lies on the surface of the mirror and it is usually denoted by P.
. Pole: It is the centre of the reflecting surface of a spherical mirror. It lies on the surface of the mirror and it is usually denoted by P.2. Centre of curvature: The centre of the sphere formed by the reflecting part of a spherical mirror is called the centre of curvature. It is generally denoted by C. this is not a part of the mirror and it lies outside the reflecting surface of the mirror. For a convex mirror, it lies behind the mirror.

3. Radius of curvature: It is the radius of the sphere formed by the reflecting part of the sphere. It is represented by R.
3. Radius of curvature: It is the radius of the sphere formed by the reflecting part of the sphere. It is represented by R.4. Principal axis: It is the straight-line parring through the pole and centre of curvature of the spherical mirror. This is normal to the mirror at its pole.

Principal axis: It is the straight-line parring through the pole and centre of curvature of the spherical mirror. This is normal to the mirror at its pole.5. Principal focus: The incident rays coming parallel to the principal axis after reflection appear to diverge from a common point on the principal axis, this point is called the principal focus of a convex mirror. It is usually denoted by F.
