Light waves from two coherent source arrive at two points on a screen with path difference `0 and lambda//2`. Find the ratio of intensities at the points.

Answer the following: (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 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 a Young's double slit experiment, using mono-chromatic light of wavelength lambda , the intensity of light at a point on the screen where the path defference is lambda is k units. Find the intensity at a point where the path difference is lambda//3 .

Assertion: Two identical waves due to two coherent sources interfere at a point with a phase difference of (2pi)/3 , then the resultant intensity at this point is equal to the individual intensity of the sources. Reason: A phase difference of (2pi)/3 is equivalent to a path difference of lambda/3 .
