Question

if the image is formed by a mirror fall all positions of the object placed in front of it is always diminished, erect, 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 (a) define the radius of curvature of spherical mirrors. find the nature and focal length of a spherical mirror whose radius of curvature is +24cm?

Answer 1

Focal length of the spherical mirror is = +24 cm, therefore it is a convex mirror.

Explanation:

• The image formed by a mirror for all positions of the object placed in front of the mirror is the convex mirror.
• In which image formed will always be erect and virtual and diminished.
• The ray of light is coming from distant and making the image between the P and F point of the mirror.
• It is used in front light of cars to reflect the light.

(b) Radius of curvature:

• Radius of curvature of a spherical mirror is defined as "the radius of the original sphere from which the mirror is belonged from".
• It is away from the pole of the mirror and the centre of the spherical shell.
• Thus Focal length of the spherical mirror is =+24 cm, so this a kind of convex mirror.

Answer 2

(a) The image formed by a mirror for all positions of the object placed in front of the mirror is the convex mirror.In which image always form diminished, erect and virtual. Here the ray of light is coming from distant and making the image between the P and F.

The concave mirror is used in front light of cars to reflect the light.

(b) Radius of curvature:

The radius of curvature of a spherical mirror is defined as the radius of the original sphere from which the mirror is belonged from.This is distant from the pole of the mirror and the centre of the spherical shell.

Given,

Focal length of the spherical mirror is=+12cm, so this a kind of convex mirror.
