Question

State the relation between Object distance,
Image distance and focal length

of a spherical mirror (concave or convex ) mirror






​

Answer 1

Answer:

Object distance means what is the distance between pole and object. Image distance means when image is formed then the distance between pole and image is called image distance. Focal length is the distance between pole and the principal focus of the mirror

Answer 2

For both concaveand convex lens,

1/f=1/v-1/u

where f= focal length

u= object distance

v=image distance
