The intensity of interference waves in an interference pattern is same as I_(0) . The resultant intensity at the point of observation will be

(i) tan3 theta tan7 theta + 1 = 0 (ii) sin ^ (2) theta = sin ^ (2) alpha

Monochromatic light waves of intensities I_(1) and I_(2) , and a constant phase difference phi produce an interference pattern. State an expression for the resultant intensity at a point in the pattern. Hence deduce the expressions for the resultant intensity, maximum intensity and minimum intensity if I_(1)=I_(2)=I_(0).

Intensity level of intensity l is 30 dB. The ratio I/I_(0) is (where I_(0) is the threshold of hearing)

The intensity of the central fringe obtained in the interference pattern due to two identical slit sources is I. When one of the slits is closed then the intensity at the same point is I_0 . Then the correct relation between I and I_0 is :

Two identical coherent waves each of intensity I_(0) are producing interference pattern. What are the values of resultant intensity at a point of (i) constructive interference (ii) destructive interference ?

In an interference arrangement similar to young's double slit experiment the slits S_(1) and S_(2) are illuminated with coherent microwave sources each of frequency 10^(6)Hz the sources are synchronized to have zero phase difference. the slits are separated by a distance d=150.0m. The intensity I(theta) is measured as a funtion of theta , where theta is defined as shown. if I_(0) is the maximum intensity then I(theta) for 0lethetale90^(@) is given by:

(cos theta + i sin theta) ^ (n) = cos n theta + i sin n theta
