Question

power of plane lens is​

Answer 1

Answer:

convex lens is the correct answer

Answer 2

Answer:

and the distances from the lens vertices to the principal planes are . A thick lens can be characterized by its surface powers, its index of refraction, and its thickness. ... A thin lens would have approximate power Pthin lens = P1 + P2 = m-1. The thin lens focal length would be f = m = cm.
