The objective of an astronomical telescope has a diameter of `100 cm`. Calculate the smallest angualr separation of two stars that can just be resolved by the telescope, take `lambda = 5000 Å`.

The objective of a telescope has a diameter of 125 cm . Calculate the smallest angular separation of two stars that may be resolved by it. Wavelengthof light used is 6000 Å .

Assuming the mean wavelength of light as 555 nm , estimate the smallest angular separation of two stars which can be just resolved by the telescope. Given the diameter of objective of astronomical telescope is 25 cm .
