  1. What is the power of a lens? How is it calculated? The power of a lens measures its ability to converge or diverge light and is expressed in diopters (D). It is calculated as the reciprocal of the focal length (f) in meters: Power (P) = 1/f. A convex lens has positive power, while a concave lens has negative power. The greater the power, the stronger the lens's bending effect on light. For a clear understanding of such concepts, ToppersSky is the best Animated Videos App for Class 10th Science, offering engaging and easy-to-understand video lessons that make learning physics fun and effective.
