Question

what is chromatic aberration ? Determine the maximum and minimum magnifying power of a convex lens of a focal length 20 cm.
​

Answer 1

Answer:

Your answer is given below.

Explanation:

The combination of lenses of small wavelengths is not easy. The more important is, if you decrease the focal length, then both defects will become stronger. Hence, in general magnifying power of simple convex lens is not possible more than 3. By system in which defect is solved this limit can be increased to 10 times or more than it.
