ANSWER
The focal length of theconcave mirror does not change when it is immersed in water because focal length of amirror does not depend upon the refractive index of the medium. ... Therefore, when aconvex lens is dipped into water, its focal length increases.
A convex lens is immersed in a liquid of refractive index greater than that of glass. ... When a convex lens is dipped in water what effect does that have on the focal length? A convex lens offocal length 120cm in air is immersed in water whose refractive index is 4/3.
