Question

What is the relationship between focal length and magnification in sperical mirrors?

Answer 1

The relation between focal length and magnification is in the formula where the formula is

M = f / -f ( the distance between the object and the pole. )
Is the formula is written in the form of focal length then the relationship between magnification is in the form of focus and focus lens it means the answer is and the relationship between the magnification and focus is there in formula where is focal length

It will help you to understand how is formula is hm the answer is help you

Answer 2

Here is ur answer
mirror formula is
1/ f = 1 / v + 1/ u
so on solving the equation
v = fu / u- f
on dividing this equation by u
v / u = f / u - f
so as we know
m = v / u
so,
m = f / u- f
