Lab Manual Questions1. Draw ray diagrams for the distant object and conjugate foci methods used todetermine the focal lengths of the lenses. 2. A concave lens made out of air is immersed in water. Will it form a real image thatcan be focused on a screen? Why or why not?
3. If a convex lens with an index of refraction of 1.5 and a focal length of 20 cm wereimmersed in a fluid whose index of refraction is also 1.50, what is the new focallength of the lens.
4. What are the major sources of uncertainty in this experiment?
