What is resolving power of an optical instrument?

Resolving power is the ability of an imaging device to separate (i.e., to see as distinct) points of an object that are located at a small angular distance or it is the power of an optical instrument to separate far away objects, that are close together, into individual images.

What affects the resolution of an optical telescope?

Firstly, resolution is inversely proportional to the size of the primary mirror. The larger the diameter of the mirror, the smaller the value of θ, the theoretical resolution. A large telescope therefore theoretically can resolve more detail than a small telescope at a given wavelength.

What are two ways you can increase the resolution when using telescopes?

There are two motives for increasing the telescope aperture: greater light-gathering power and the potential for higher spatial resolution. The largest of these telescopes require segmented mirrors, since current technology does not provide for the fabrication of monolithic mirrors with diameters much larger than 8m.

What do you mean by resolving power of an optical instrument What is the resolving limit of human eye?

The ability of an instrument to separate or distinguish close adjacent images is called the resolving power of that optical instrument . Resolving power and resolving limit are reciprocal. If wavelength of light is λ and diameter of objective is d, then resolving limit of a telescope , θ=1.22λd.

What is resolving power of an optical instrument obtain an expression for resolving power of telescope?

Ans: Resolving power of a telescope =d1.22λ.

What is the resolving power of the telescope?

Resolving power is another important feature of a telescope. This is the ability of the instrument to distinguish clearly between two points whose angular separation is less than the smallest angle that the observer’s eye can resolve.

Which telescope has a higher resolving power?

The Hubble Space Telescope
Answer: The Hubble Space Telescope (HST) has a highest resolution of about 0.03 arcseconds, while the Very Long Baseline Array (VLBA) makes images with a resolution smaller than 0.001 arcsec. So, the VLBA has the HST beat when it comes to picture resolution.
