Types of oscillators: simple harmonic, damped and forced.
1. Fringe width in a particular YDSE measured to be đť›˝. 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 ?
2. 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?
3. In Young’s double slit experiment, the distance between the two slits is made half, then the fringe width will become ?
4. In the Young’s double slit experiment, for which colour the fringe width is least ?
