Question

explain this steps of mirror formula ​

Answer 1

Step-by-step explanation:

1/v + 1/u = 1/f

1/v = 1/f - 1/u (here:- +1/u goes on right side and changes it sign to (-)

• 1/v = 1/-10 - (1/-30)

(here :- the values of (f) and (u) are put then solved )

• 1/v = -3 + 1 / 30

• 1/v = -2 / 30 or -1 / 15
