Experiment name
Fringe width in a particular YDSE measured to be `beta`. What will be the fringe width if the wavelength of the light is doubled,the separation between the slits is halved and separation betweeen the screen and slits is tripled?
Two coherent sources are `0.3mm` apart . They are `1m` away from the screen . The second dark fringe is at a distance of `0.3cm` from the center. The distance of the fourth bright fringe from the centre is?
