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 differenct positions, a distance x apart. The two real images have magnifications `m_(1)` and `m_(2)`, respectivelly `(m_(1)gtm_(2))`. Then,

A lense 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 distance x apart. The two real images have magnification m_1 and m_2 respectively (m_1gtm_2). Choose the correct statement(s).

A lense 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 distance x apart. The two real images have magnification m_1 and m_2 respectively (m_1gtm_2). Choose the correct statement(s).

The distance between object and the screen is D. Real images of an object are formed on the screen for two positions of a lens separated by a distance d. The ratio between the sizes of two images will be:

The distance between object and the screen is D. Real images of an object are formed on the screen for two positions of a lens separated by a distance d. The ratio between the sizes of two images will be:

A convex lens of focal length f is placed somewhere in between an object and a screen. The distance between the object and the screen is x . If the numerical value of the magnification produced by the lens is m , then the focal lnegth oof the lens is .
