A compound microscope has a magnification of 30. The focal length of its eye-piece is 5 cm. Assuming the final image to be formed at least distance of distinct vision (25 cm),calculate the magnification produced by the objective.

Draw a ray diagram of compound microscope for the final image formed at least distance of distinct vision?

The focal length of the objective an astoomical telescope is 75 cm and that of the eye-piece is 5 cm.If the final image is ofrmed at the least distance of ditinct vision from the eye,calculate the magnifying power of the telescope.

What is the magnifying power of an astronomical telescope when the final image of a distant object is formed at least distance of distinct vision?

Define magnification of an astronomical refracting type telescope and find an expression for it when the final image is formed at least distance of distinct vision.

A compound microscope consists of an objective lens of focal length 2.0 cm and an eyepiece of focal length 6.25 cm separated by a distance of 15 cm. How far from the objective should an object be placed in order to obtain the final image at the least distance of distinct vision (25 cm)? What is the magnifying power of the microscope in?

Draw a labelled ray diagram showing the formation of a final image by a compound microscope at leat distance of distinct vision.

The focal length of a convex lens is 30 cm and the size of image is quarter of the object.Them,the object distance is

A telescope has an objective of focal length 50 cm and eye-piece of focal length 5 cm.the last distance of distinct vision is 25 cm.The telescope is focussed for ditinct vision on a scale 200 cm awya from teh objective.Caculate the magnification produced.
