WebThe focal length of the lens is the distance from the center of the lens to the spot, given to be 8.00 cm. Thus, f = 8.00 cm. To find the power of the lens, we must first convert the focal length to meters; then, we substitute this value into the equation for power. This gives P = 1 f = 1 0.0800 m = 12.5 D P = 1 f = 1 0.0800 m = 12.5 D. Discussion WebAnd, again, we have to subtract one over 12, and that's all gonna have to be equal to one over the image distance. So now on the left-hand side, we have negative 1/4, but that's the same as negative 3/12. So negative 3/12 minus 1/12 is the same as negative 4/12, and that's got to equal one over the image distance.
