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 function of `theta`, where `theta` is defined asa shown in fig. If `I_(0)` is hte maximum intensity, then `I(theta)` for `0 le theta le 90^(@)` is given by ltbrrgt

Options

A. `I(theta) = I_(0)//2 ` for `theta = 30^(@)`
B. `I(theta)=I_(0)//4` for `theta=90^(@)`
C. `I(theta)=I_(0)` for `theta = 0^(@)`
D. `I(theta)` is constant for all value of `theta `

Answer

C
