Assertion             :       For best contrast between maxima
Question

Assertion             :       For best contrast between maxima and minima in the interference pattern of Young?s double slit experiment, the intensity of light emerging out of the two slits should be equal. Reason                 :   The intensity of interference pattern is proportional to square of amplitude.

A
If both assertion and reason are true and the reason is the correct explanation of the assertion.

B
If both assertion and reason are true but reason is not the correct explanation of the assertion.

C
If assertion is true but reason is false.

D
If the assertion and reason both are false.

E
If assertion is false but reason is true.

                   When intensity of light emerging from two slits is equal, the intensity at minima, Imin=(Ia−−√−Ib−−√)2=0, or absolute dark. It provides a better contrast.

Question 1
A narrow tube is bent in the form of a circle of radius R, as shown in the figure. Two small holes S and D are made in the tube at the positions right angle to each other. A source placed at S generated a wave of intensity which is equally divided into two parts : One part travels along the longer path, while the other travels along the shorter path. Both the part waves meet at the point D where a detector is placed. The maximum value of to produce a minima at D is given by :
