Описание: In this video, we solve an important NDA 2022 Physics Question on power of combination of lens. Two convex lenses of focal lengths 50 cm and 25 cm are placed in contact, and we calculate the net power of the lens system using the lens power formula. This concept is very useful for NDA, CDS, CBSE Class 12 Physics and other competitive exams. Watch till the end to learn the step–by–step solution as well as the quick shortcut to solve similar questions in seconds.
