A student investigates the image of an object formed on a screen by a converging lens, as shown in Fig. 2.1. ho object lens screen d Fig. 2.1 The student measures the height ho of the object and the distance d from the lens to the screen. The height hi of the image is measured as shown in Fig. 2.2. hi screen Fig. 2.2 The experiment is repeated for different values of d. It is suggested that hi and d are related by the equation f d t h h 1 2 1 o i + = + c m where f is a property of the lens called the focal length and t is the thickness of the lens. h
