An object is to be seen through a simple microscope of power 10D. Where should the object be placed so as to produced maximum angular magnification ? The least distance for distinct vision is 25 cm.

An object is to be seen through a simple microscope of power 10 D . Where should an object be placed to produce maximum angular magnification ? Least distance of distinct vision is 25 cm .

An object is to be seen through a simple microscope of focal length 12 cm. Where should the object be placed so as to produce maximum angular magnification? The least distance for clear vision is 25 cm.

A 20 D lens is used as a magnifier. Where should the object be placed to obtain maximum angular magnification? (Given, D=25 cm).

A simple microscope has a focal length of 5 cm . The magnification at the least distince of distinct vision is-

Convex lens of focal length f is used as simple microscope. D is the least distance for distinct vision.

An object is seen through a simple microscope of focal length 20 cm. Find the angular magnification produced, if the image is formed at 30 cm from the lens.

A simple microscope of power 15 D is used to see an object. If the least distance of distinct vision is 25 cm, where should the object be placed so as to produce maximum angular magnification?

(a) An object is seen through a simple microscope of focal length 12cm . Find the angular magnification produced if the image is formed at the near point of the eye which is 25cm away from it. (b) A 10D lens is used as a magnifier. Where shold the object be placed to obtain maximum angular magnification for a nirmal eye (near point = 25cm) ?

Magnifying power of a simple microscope A is 1.25 less than that of a simple microscope B. If the power of the lens used in B is 25 D, find the power of lens used in A. Given that distance of distinct vision is 25 cm.
