What is the optical power of the system of two lenses, if the optical power of the first is 5 diopters, the focal length of the second is 40 cm.
Let’s find the focal length of the second lens through the formula:
D = 1 / F → F = 1 / D = 1 / F = 1 / 0.4 m = 2.5 diopters.
Answer: 1) 67о; 2) 2.5 diopters.
