WebMay 26, 2024 · Problem 1: What is the length of the image produced by placing the object of 10cm away from a convex lens of focal length equal to 5 cm? Solution: Given that, The focal length, f is 5 cm. As the object is on the left side so, the object distance, u is -10 cm. Using the lens formula, the focal length is given by: 1/f = 1/v – 1/u Webf = 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.
