A lens of focal length f is placed in between an object and screen at a distance D. The lens forms two real images of object on the screen for two of its different positions, a A lens of focal length f is placed in between an object and screen at a distance D. The [...]

The distance between an electric lamp and a screen is d= 1 m. A convergent lens of focal length f = 21 cm is placed between the lamp and the lens such that a sharp image of the The distance between an electric lamp and a screen is d= 1 m. A convergent lens of [...]

In displacement method, the distance between object and screen is 96 cm. The ratio of lengths of two images formed by a converging lens placed between them is 4. Then, In displacement method the distance between object and screen is 96 cm. The ration of lengths of two images formed by a converging lens placed [...]
