MHT CET 2026 Physics question
A simple microscope is a combination of two lenses in contact. Their powers are +20D and -4D. The distance of distinct vision is 25 cm. When seen through the microscope, the size of the image of an object 3 mm high is
Answer: (B)
Solution
Lenses in contact: , so . For a simple microscope with the final image at the least distance of distinct vision , the magnification is \dfrac{D}{f}$ = 1 +
