Question

You are provided with two convex lens of focal lengths 25cm and 50 cm respectively. Which lens will you use to obtain more convergent light? Justify your answer with a ray diagram​

Answer 1

Answer:

Which lens will you use to obtain more convergent light? Justify your answer, with a ray diagram(use 5cm as 1cm for diagram). Both lens will converge light equally. The only difference will be the point of convergence as in one case it will be 25 cm and in other case of lens with focal length will converge at 50 cm.
