Find the power of a concave lens of focal length 2 m
Question
Find the power of a concave lens of focal length 2 m
Solution
To find the power of a concave lens of focal length 2 m, we can use the formula:
Power (P) = 1 / focal length (f)
Given that the focal length (f) is 2 m, we can substitute this value into the formula:
P = 1 / 2
Simplifying the equation, we find:
P = 0.5
Therefore, the power of the concave lens is 0.5 diopters.
