Focal length physics
WebAug 13, 2014 · f = focal length. • ( 5 votes) santhosh prabahar 5 years ago If you did this problem using the equation 1/f=1/v-1/u, you would get the answer as 6 cm. According to the same sign convention using which the above mentioned formula was derived, the answer 6 cm means the same as -6 cm when viewed from different sign conventions. The focal length of a lens refers to the distance between the focus (or one of the foci) to the center of the thin lens. It can also be calculated using the equation 1/do + 1/di = 1/f. What is a...
