2. An object is placed at the left of a converging lens and a image at 20 cm to the right of this lens is formed on a screen. Now if we place a new lens 15 cm to the right of the converging lens, you have have to move the screen 25 cm to the right to get a clear image formed by this diverging lens. (a) What is the focal length of this new lens? 6) Is this new lens a converging lens or diverging lens?
