The aperture of the objective lens of a telescope is made large so as to

The diameter of the objective lens of a telescope is 5.0m and wavelength of light is 6000 Å . The limit of resolution of this telescope will be

Diameter of the objective lens of a telescope is 250 cm. for light of wavelength 600 nm. Coming from a distance object, the limit of resolution of the telescope is close to :

The image formed by an objective of a telescope is-

The aperture and focal length of the objective of telescope are large, why?

The focal lengths of the objective and eye lenses of a telescope are respectively 200 cm and 5 cm . The maximum magnifying power of the telescope will be

The focal lengths of the objective and eye lenses of a telescope are respectively 200 cm and 5 cm . The maximum magnifying power of the telescope will be

The aperture of a telescope is made large, because

Assertion : The focal length of objective lens in telescope is much more than that of eye piece. Reason : Telescope has high resolving power due to large focal length.

The diameter of the lens of a telescope is 0.61 m and the wavelength of light used is 5000 Å. The resolution power of the telescope is

A: The resolving power of a telescope decreases on decreasing the aperture of its objective lens. R: The resolving power of a telescope is given as D/(1.22 lamda) where D is aperture of the objective and lamda is the wavelength of light.
