When an object is placed on the principal axis of a convex lens at two different positions, it produces the image with magnifications +2 and -4 respectively. How many times it produces the image with magnifications +2 and -4 respectively. How many times When an object is placed on the principal axis of a convex [...]

A lens forms a diminished and erect image of an object. The magnification is 1/4. Find the ratio of distances between object and focus and focus and image.

An equiconcave diverging lens of focal length F is cut into two equal halves. The two halves are turned around and joined with some liquid between them. The lens obtained is converging An equiconcave diverging lens of focal length F is cut into two equal halves. The two halves are turned around and joined with [...]

A convex lens of focal length 20 cm and another plano convex lens of focal length 40 cm are placed co-axially (see figure). The plano convex lens is silvered on plane surface. A convex lens of focal length 20 cm and another plano convex lens of focal length 40 cm are placed co-axially (see figure). [...]

In an optics experiment, with the position of the object fixed, a student varies the position of a convex lens and for each position, the screen is adjusted to get a clear image of the object. a student varies the position of a convex lens and for each position In an optics experiment the screen [...]
