Question

in sperical mirror write the relationship between object distance, image distance and focal length.

Answer 1

Explanation:

In spherical mirrors,the realation between object distance, image distanceand focal length is

1/f =1/u+1/v.

◆There are 2 types of spherical mirrors.

◆thry are concave and convex mirrors.

◆Concave mirrors form virtual and real images.

◆Convex mirror forms virtual image to any position of the object.

★Concave mirrors are used in solar heaters,make up mirrors,shaving mirrors etc

◆Convex mirrors are used in shop security, rear view mirrors in vehicles.

Answer 2

Answer :

$\rule{100}2$

In a spherical mirror,

Relation between object distance, image distance and focal length is :-

$\sf => \dfrac{1}{f}=\dfrac{1}{u}+\dfrac{1}{v}$

Here,

• ' f ' indicates focal length
• ' v ' indicates image distance
• ' u ' indicates object distance

Additional Information :

→ Image distance means the distance between image and pole.

→ object distance means distance between object and pole.
