If intensity of each wave in the observed interference pattern in Young’s double slit experiment is `I_0`. Then for some point P where the phase difference is phi, intensity I will be :

The fringe pattern observed on Young's double-slit experiment is

Consider interference between waves form two sources of intensities I&4I .Find intensities at point where the phase difference is pi

Do you think that interference pattern in Young's double slit experiment is the consequence of the superposition of the diffracted waves from the two slits?

In Young's double slit experiment, if one of the slit is closed fully, then in the interference pattern

In YDSE, the slits have different widths. As a result, amplitude of waves from slits are A and 2A respectively. If I_(0) be the maximum intensity of the intensity of the interference pattern then the intensity of the pattern at a point where the phase difference between waves is phi is given by (I_(0))/(P)(5+4cos phi) . Where P is in in integer. Find the value of P ?

The intensity of each of the two slits in Young's double slit experiment is I_0 . Calculate the minimum separation between the two points on the screen where intensities are 2I_0 and I_0 . Given, the fringe width equal to beta.

(a) Why are coherent sources necessary to produce a sustained interference pattern ? (b) In Young's double slit experiment using monochromatic light of wavelength lamda , the intensity of light at a point on the screen where path difference is lamda , is K units. Find out the intensity of light at a point where path difference is lamda//3 .
