For a system of lenses, the net power of the system is P = P 1 + P 2 + P 3. The focal length of the net system can be written as. When the refractive index of the medium is less than that of the lens. When the refractive index of the medium is equal to that of the lens. Therefore, the focal length of the lens becomes infinity and the power becomes zero.. When the refractive index of the medium is greater that of the lens,. Therefore, the focal length of the lens decreases..
