Consider the interference at P between waves emitting from three coherent sources in the same phase located at S_(1) , S_(2) and S_(3) . If the intensity due to each source is I_(0)=12Wm^(-2) at P and (d^(2))/(2D)=(lamda)/(3) then what will be the resultant intensity (in Wm^(-2) ) at P?

Interference fringes are obtained due to the interference of wave from two coherent sources of light with amplitudes a_(1) and a_(2)(a_(1)=2a_(2)) . The ratio of the maximum and minimum intensities of light in the interference pattern is

The path length difference between two waves coming from coherent sources for destructive interference should be

(a) In Young's double slit experiment, the two slits are illuminated by two different lamps having same wavelength of light. Explain with reason, whether interference pattern will be observed on the screen or not. (b) Light waves waves from two coherent sources arrive at two points on a screen with path differences of 0 and lamda//2 . Find the ratio of intensities at the points.

In the case of light waves from two coherent sources S_(1) and S_(2) , there will be constructive interference at an arbitrary point P, the path difference S_(1)P - S_(2)P is
