Calculated the numerical aperture of a microscope required to just resolve two points separated by a distance of 10^(-4) cm, using light of wavelength 5.8xx10^(-5)cm .

Calculate the aperture of the objective of a telescope which may be used to just resolve two stars separated by 6.1 times 10^-6 radian, if light from the star has a wavelength of 550 nm.

A telescope of diameter 500 cm is used to resolve two points on the moon. Calculate the separation between the points . Take distance of the moon from the Earth =4 xx 10^(10) cm , and wavelength of light most sensitive to eye =5.5 xx 10^(-5) cm .

The numerical aperture of a microscope is 0.31. If the wavelength of light used in 600 nm, calculate the resolving power of the microscope.

First diffraction minima due to a single slit of width 1.0 xx 10^(-5)cm is at 30^(@) . The wavelength of light used is :

A microscope is used to resolve two self luminous objects separated by a distance of 5 xx 10^(-5)cm and placed in air. What should be the minimum magnifying power of the microscope in order to see the resolved images of the objects? The resolving power of the eye is 1.5 and teh least distance of distinct vision is 25 cm.
