Figure shows a standard two slit arrangement with slits `S_(1), S_(2). P_(1), P_(2)` are the two minima points on either side of P (Figure). At `P_(2)` on the screen, there is a hole and behind `P_(2)` is a second 2-slit arrangement with slits `S_(3), S_(4)` and a second screen behind them.

Figure EP 10.5 shows a standard two slit arrangement with slits S_1 , S_2 , P_1 , P_2 are the two minima points on either side of P. At P_2 on the screen, there is a hole and behind P_2 is a second 2-slit arrangement with slits S_3 , S_4 and a second screen behind them.

Figure shows a standard two slit arrangement with slits S_1,S_2. Now, P_1,P_2 are the two minima points on either side of P. At P_2 on the screen, there is a hole and behind P_2 is a second 2-slit arrangement with slits S_3,S_4 and a second screen behind them .

In a Young's double slit experiment, let S_(1) and S_(2) be the two slits, and C be the centre of the screen. If angle S_(1)CS_(2)=theta and lambda is the wavelength, the fringe width will be

In a Young's double slit experiment, let S_(1) and S_(2) be the two slits, and C be the centre of the screen. If angle S_(1)CS_(2)=theta and lambda is the wavelength, the fringe width will be

In a Young's double-slit experiment, let S_(1) and S_(2) be the two slits, and C be the centre of the screen. If /_S_(1)CS_(2)=theta and lambda is wavelength, the fringe width will be

A coherent light is incident on two paralle slits S_(1) and S_(2) . At a point P_(1) the frings will be dark if the phase difference between the rays coming from S_(1) and S_(2) is

A monochromatic light source of wavelength lamda is placed at S. three slits S_(1),S_(2) and S_(3) are equidistant from the source S and the point P on the screen S_(1)P-S_(2)P=lamda//6 and S_(1)P-S_(3)P=2lamda//3 . if I be the intensity at P when only one slit is open the intensity at P when all the three slits are open is-
