In a certain camera, a combination of four similar thin convex lenses are arranged axially in contact. Then the power of the combination and the total magnification in comparison to the power $(p)$ and magnification $(m)$ for each lens will be, respectively

Options:

Answer:

Solution:

When a combination of lens is used then total power $P_{net} = P + P + P + P = 4 P$ Total magnification $m_{net} = m \times m \times m \times m = m^{4}$
