what happens to interference pattern in young doble slit experiment ,if the main source is not on central line

answered-by-expert Expert Answer
In Young's double slit experiment, the source is on the centre line between the slits and thus the central bright fringe appears at O. This is because the distance travelled by the rays SCO and SDO are equal as shown in figure (a).
 
 
If the source is moved, say if we move it upwards at point S' as shown in figure (b), the central bright fringe will appear at point O'. Here the distance traveled by rays SCO and SDO are not equal. Therefore, when the source is moved upwards from the central line, the central bright fringe will move downwards and vice-versa.

In Young's double slit experiment, the two slits are separated by 0.28mm and the screen is placed at a distance of 1.4m away from the slits. the distance between the centre fringe and the fifth dark fringe is measured to be 1.35cm . calculate the wavelength of light used. Also find the fringe width if the screen is moved 0.4m towards the slits, for the same experiment set up.

if separation between the two slits is increased till fringes are observed then what will happen to angular separation of fringes (my thought is here  fringes are not observed  and they are increasing till fringes show up ...so until then what will happen to angular width if we increase d-slit separation..does angular width increases or remains same

We for equal wave intensities the intensity at a point is given by straight I to the power of apostrophe equals 4 Icos squared open parentheses straight ϕ over 2 close parentheses but where does the formula straight I to the power of apostrophe equals Icos squared open parentheses straight ϕ over 2 close parentheses come from??
