A microscope is having objective of focal length and eye piece of focal length 6cm. If tube length 30cm and image is formed at the least distance of distant vision, what is the magnification prodcut by the microscope. (take D=25cm)

A microscope is having objective of focal length 1 cm and eyepiece of focal length 6 cm. If tube length is 30 cm and image is formed at the least distance of distinct vision, what is the magnification produced by the microscope ? Take D=25 cm.

A compound microscope having magnifying power 35 with its eye - piece of focal length 10 cm. Assume that the final image is at least distance of distinct vision then the magnification produced by the objective is

A compound microscope having magnifying power 35 with its eye - piece of focal length 10 cm. Assume that the final image is at least distance of distinct vision then the magnification produced by the objective is

A microscope consists of an objective of focal length 1.9 cm and eyepiece of focal length 5 cm. The two lenses are kept at a distance of 10.5 cm. If the image is to be formed at the least distance of distinct vision, the distance at which the object is to be placed before the objective is (least distance of distinct vision is 25 cm)

The focal lengths of the objective and the eyepiece of a compound microscope are 1 cm and 5 cm respectively and the distance between the centres of the lenses is 15 cm . If the final image is formed at the least distance of distinct vision , what is the magnifying power of the microscope ?

A compound microscope has an objective of focal length 1 cm, an eye piece of focal length 2.5 cm and a tube of length 15 cm. Find its magnification for normal adjustment.

The focal length of objective and eye-piece of a telescope are 100 cm and 5 cm respectively. Final image is formed at least distance of distinct vision. The magnification of telescope is

A compound microscope has a magnification of 30. The focal length of eye piece is 5 cm. Assuming the final image to be at least distance of distinct vision, find the magnification . produced by the objective.
