It will be 50 cm because lesser the focal lenght fastest and clearest will be the nature of image.
U = -25
v=-50
1÷f=1÷v - 1÷u
1÷-50 + 1÷25
= -1÷50
f = 50
U = -25
v=-50
1÷f=1÷v - 1÷u
1÷-50 + 1÷25
= -1÷50
f = 50
what do u mean
in case of converging lens U and V are negative only in one case and how you sure that its that case only
thik hai mere baap
how f is negative bcoz f is positive in converging lens
plz answer my question i am very much confused
