Assertion : By increasing the diameter of the objective of telescope, we can increase its range. Reason : The range of a telescope tells us how far away a star of some standard brightness can be spotted by telescope.
The aperture of telescope is increases to
The aperture and focal length of the objective of telescope are large, why?
On increasing the diameter of a circle by 40% its area will be increased by
Why is the aperture of objective lens of a telescope taken large ?
What is the resolving power of a telescope if the diameter of the objective of the telescope is 1.22 m and the wavelength of light is 5000 Å ?
