A converging lens 1 A diverging lens diverges it. The focal length of a lens is the distance between its optical centre \( C \) 2. and its \( 12.4 \) Test 1. With the help of a diagram, describe how a converging lens is different from a diverging lens in terms of their structure and their effect on light. 2. Figure \( 12.54 \) shows a diagram of light rays passing through a thin converging lens. Is the diagram correct? State your reasons. 3. With the help of a diagram, define the - Figure \( 12.54 \) focal length of a thin converging lens. Why is this diagram correct/or not?
