Define resolving power of a microscope and write one factor on which it depends
Advertisements
उत्तर
Resolving power of a microscope is the ability of the microscope to form separate image of two closely object placed near the microscope.
Resolving power of microscope is given by
`R.P. = (2μsinθ)/λ `
It is clear from the above equation, resolving power depends on the wavelength (λ) of the light used.

Draw a labelled ray diagram showing the formation of a final image by a compound microscope 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

What is the magnifying power of the microscope in each case?
Magnifying power of a simple microscope is inversely proportional to the focal length of the lens. What then stops us from using a convex lens of smaller and smaller focal length and achieving greater and greater magnifying power?
How is 'limit of resolution' related to resolving power of a microscope ?
Suggest two ways by which the resolving power of a microscope can be increased?
