A convex lens of focal length 1 meter and a concave lens fo focal length 0.25 meter and kept 0.75 meter apart. A parallel beam of light first passes through the ocnvex lens, then through the concave lens and comes to a focus 0.5m away from the concave lens.

To solve the problem step by step, we will analyze the behavior of the light as it passes through the convex and concave lenses. ### Step 1: Understanding the Setup We have two lenses: - A convex lens with a focal length (F1) of 1 meter. - A concave lens with a focal length (F2) of -0.25 meters (the focal length of a concave lens is taken as negative). The distance between the two lenses is 0.75 meters. ...
