Question
A doctor prescribes spectacles to a patient with acombination of a convex lens of focal length 25 cm then the power of spectacles will be :
Options
A.- 6.5 D
B.1.5 D
C.-1.5 D
D.-8.5D
Solution
For combination of lenses, power
P = P1 + P2 =
= - 1.5 D
P = P1 + P2 =
= - 1.5 DCreate a free account to view solution
