In a displacement method using lens, we obtain two images for separation of the lens d. One image is magnified as much as the other is diminshed . If m is the magnification of one image, find the focal length of the lens.

To find the focal length of the lens in the displacement method, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Problem**: We have a lens that produces two images when the lens is displaced. One image is magnified by a factor \( m \) while the other image is diminished by the same factor. This implies that if the magnification of the first image is \( m_1 = m \), then the magnification of the second image will be \( m_2 = \frac{1}{m} \). 2. **Using the Formula for Focal Length**: ...
