How could you very quickly make an approximate measurement of the focal length of a converging lens? Could the same method be applied if you wished to use a diverging lens? Explain.
w9-19 physics An object is placed 20.0 cm from a converging lens with focal length 15.0 cm (see the figure, not drawn to scale). A concave mirror with focal length 10.0 cm is located 76.0 cm to the right of the lens. Light goes through the lens, reflects from the mirror, and passes through the lens again, forming a final image. d=76.0 What is the location of the final image? ______cm to the left of the lens
