Question

An object is kept at a distance of 30 cm from diverging lens of focal length 15 CM. At what distance the image is formed from the lens? find the magnification of the image​

Answer 1

Distance to the left focal point ( which is right of the lens for a negative lens ) is 45 cm. In focal lengths that is 3 focal lengths. Meaning that the magnification will be 1/3 and the image qill be 1/3 focal lengths = 5 cm from the right focal point ( which is to left to the lens for a diverging one ). That is 10 cm from the lens on its left side.
