Question

mirror formulas with figu​

Answer 1

Answer:

From the figure given above, it is obvious that the object AB is placed at a distance of U from P which is the pole of the mirror. From the diagram we can also say that the image A1B1 is formed at V from the mirror. This was the derivation of mirror formula.

Answer 2

Answer:

1/image distance +1/object distance = 1/focal length

OR

1/v + 1/u = 1/f

Where. v=distance of image from mirror

u=distance of object from mirror

f=focal lenght of the mirror

Explanation:

Mirror formula gives the relationship between image distance,object distance and focal length of a spherical mirror.
