The lens-makers' equation applies to a lens immersed in a liquid if n in the equation is replaced by n2/n1. Here n2 refers to the index of refraction of the lens material and n1 is that of the medium surrounding the lens.

(a) A certain lens has focal length 73.7 cm in the air and index of refraction 1.55. Find its focal length in water.

(b) A certain mirror has focal length 73.7 cm in the air. Find its focal length in water.
