Using analytical method for interference bands, obtain an expression for path difference between two light waves.
Determine the change in wavelenght of light during its passage from air to glass, if the refracrtive index of glass with respect to air is 1.5 and the frequency of light is 5 x 1014 Hz. Find the wave number of light in glass (velocity of light in air c = 3 X 108 m/s)
A point is situated at 6.5 em and 6.65 em from two coherent sources. Find the nature of illumination at the point, if wavelength of light is 5000 Å
The minimum angular separation between two stars is 4 × 10−6 rad, if telescope is used to observe them with an objective of aperture 16 cm. Find the wavelength of light used.
