Answered by aarohischander6511

Answer:

Power of convex lens of focal length 2m

Note: The power of the lens is said to be 1 dioptre if the focal length of the lens is 1metre. That means, if the corrective power of the lens is +0.5D, the required lens is a convex lens of focal length +2m. In the same way, a power of -2.0D means a concave lens of focal length -0.5m.
