What is the difference in the interference patterns formed by two slits 10-4 apart as compared to a diffraction grating containing! 04 slits_cm?
Step 1 of 1
The intensity of the light falling on the screen is chaging gradually from bright to dark in double slit interference .
Because there are only two slits, The bright at the center of the two slits is has the highest intensity. The intensity of the other fringes around the central one gets weaker as in the figure. As in the figure.
For diffraction grating there are multiple slits. Every pair of slit has its one central bright fringe (primary maxima) and has secondary maxima. So the fringes of difration gratings are sharper and brighter than the double slits`s
The double slits 10-4cm apart and diffraction grating having 104 lines/cm both have the same slit saparation. So fringe separation of both are the same the difference is diffraction grating has sharper, thinner and brighter bright fringes.
