Question

if a convex lens and a concave lens of the same power combined together what will be the total power​

Answer 1

Answer:

p= P1+ P2

power has been added by both the lens and mirror

Answer 2

Answer:

you have a combination of concave and convex lens both have a focal length of 10 cm . ... Concave lens has a focal length of -10cm or -0.1m. If you have a combination of lens, then you can calculate net power or focal length of combination by the formula :- (I/net focal length) = (1/f1)+(1/f2)
