Question:medium
Two convex lenses of different focal lengths are in contact with each other. If the focal length of each lens is doubled, the focal power of the combination
Two convex lenses of different focal lengths are in contact with each other. If the focal length of each lens is doubled, the focal power of the combination
Show Hint
Since power is inversely proportional to focal length, doubling the focal length results in halving the power, whether it is for a single lens or a combination.
