অপবর্তন ও অপবর্তন গ্রেটিং
In a diffraction grating there are 6000 lines per cm. If light of wavelength is passed through it what is diffraction angle for second maxima?
In 1m, there are lines per m

Fraunhofer diffraction is observed on a screen placed at a distance of 0.8 m from two parallel slits separated by 0.1 x 10-3 m when the slits are illuminated by light of wavelength of 5.46 x 10-7m. What is the distance of the 3rd bright fringe from the central bright fringe?[P-2.7, IUT : 2020-21]
