Question

state the mirror formula.how does F change when object distance u from the mirror is changed?​

Answer 1

Answer:

:)

Explanation:

• The focal length 'f' of a mirror does not change with object distance 'u' as it depends upon curvature of the mirror. Now, by changing 'u' we are in fact changing the image distance according to the formula

• 1/f = 1/v + 1/u
