Statement I: For the situation shown in figure two identecal coherent light sources produce interference pattern on the screen. The intensity of minima nearest to `S_(1)` is not exactly zero.

Statement II: Minimum intensity is zero, when interfering waves have same intensity at the location of superposition.

Options

A. A is true and R is true and R is the correct explanation of A.
B. A and R are true but R is not correct explanation of A
C. A is true, R is false
D. A is false, R is true.

Answer

A

Explanation

At the location of minima, the two waves have different intensities hence minimum intensity is not equal to zero.
