Resolving Power and Resolving Limit

The resolving power of an electron microscope is higher than that of an optical microscope because the wavelength of electron is _____________ as/than the wavelength of visible light.

A spy satellite moves at a height of $50\mathrm{km}$ above the Earth's surface. The minimum diameter of a telescope objective on board of the satellite which can resolve objects separated by $2\mathrm{mm}$, using a light of wavelength $600\mathrm{nm}$ is

The human eye works like a convex lens with an aperture of $5 \mathrm{mm}$. Two bright spots of light$\lambda =5000 \stackrel{0}{\mathrm{A}}$ are $1 \mathrm{mm}$ apart. The maximum distance from the eye at which the two spots may appear well resolved is approximately

A compound microscope is designed to resolve objects which are $0.01 \mathrm{mm}$ apart. If the focal length of the objective is $4 \mathrm{cm}$ and the wavelength of the light used is $550 \mathrm{nm},$ then, the diameter of the objective is

What is the relationship between resolving power and wavelength of light?

How does the resolving power of a microscope depend on i the wavelength of the light used and II the medium used between the object and the objective lens?

On what factors does the resolving power depend?

How does the resolving power of a microscope depend on?

The ratio of resolving powers of an optical microscope for two wavelengths ${\lambda }_1=4000 \mathrm{Å}$ and ${\lambda }_2=600 \mathrm{Å}$ is

An LED display consists of $100$ pixels per ${\mathrm{cm}}^2.$ Consider that the diameter of the pupil of the eye is $5 \mathrm{mm}$ and the average wavelength of the display is $575 \mathrm{nm}.$ What is the nearest distance from the display one can be at, such that the display does not appear pixelated?

The characteristic impedance of a coaxial cable is of the order of

Resolving power of a microscope depends upon

Assume that the light of wavelength is $6000 \stackrel{\circ }{\mathrm{A}}$ coming from a star. What is the resolution limit of a telescope whose objective has a diameter of $100$ inch?

The human eye has an approximate angular resolution of, $\mathrm{\varphi }=5.8\times {10}^{-4} \mathrm{rad}$ and a typical photo printer prints a minimum of $300 \mathrm{dpi}$ (dots per inch, $1 \mathrm{inch}$$=2.54 \mathrm{cm}$). At what minimum distance $\mathrm{z}$ should a printed page be held so that one does not see the individual dots?

Two point white dots are $1 \mathrm{mm}$ apart on a black paper. They are viewed by eye of pupil diameter $3 \mathrm{mm}$ approximately. The maximum distance at which these dots can be resolved by the eye is (take wavelength of the light  $=500 \mathrm{nm}$):

Resolving power of a lens is the consequence of

The resolving power of the human eye is aprroximately-

An astronomical telescope is able to resolve two stars at an angular separation of ${10}^{–3} \mathrm{degree}$ . If wavelength of light used is $500\mathrm{nm}$,then the diameter of the objective of the telescope is
