Resolving Power of Optical Instruments

For what distance is ray optics a good approximation when the aperture is $4 \mathrm{mm}$ wide and the wavelength is $500 \mathrm{nm}$ ?

What are the conditions under which ray optics is valid?

Define angular resolving power.

What is optical instrument resolution?

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

Name the phenomenon which defines the limit of ray optics?

Ray optics is valid when characteristic dimensions are

Ray optics is valid when characteristic dimensions are

Which rule is equal to the resolution rule of first-order clauses?

When the resolution is called as refutation-complete?

Which is a refutation complete inference procedure for propositional logic?

Ray optics is valid when characteristic dimensions are

What is Rayleigh resolution?

Is angular resolution and resolving power Same?

What is the condition for validity of ray optics?

Lens Resolution depends on the distance between two distinguishable radiating points.This standard for separation is also known as the Rayleigh criterion. In symbols, the distance is $r=\frac{1.22 \lambda f}{2a}$, where f is the focal length of the lens and 2a is the diameter of the circular aperture .

List the types of resolutions in an optical instrument.

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 limit of resolution of an instrument is inversely related to it's _____.
