Solve the following questions:
Question I: A converging lens of focal length 12cm is placed 18cm in front of a plane mirror. If an object is placed 20 cm in front the lens, describe the final image and determine where it is formed.
Question II: What type of image (real or virtual) would form if the object is still placed 20 cm in front of the lens in front the lens, which is placed 18 cm in front of a convex mirror with a 20 cm radius of a curvature instead?
Question III: A converging lens of focal length 12 cm is placed in contact with a plane mirror. If an object is placed 20 cm from the lens, where the final image formed?
Please explain how you got the numbers and calculations. Thank you.
