Questions
In a Young’s double slit experiment (where d, and D have usual meaning). Each of slit individually produces the same intensity on the screen. Then select the correct option(s).
detailed solution
Correct option is A
β=Dλd=1×6000×10-1010-3=0.6 mmPhase difference between centre and any point is ϕThen Iϕ=4I0cos2ϕ2 ⇒344I0=4I0cos2ϕ2cosϕ2=±32 ⇒ϕ2=π6⇒ϕ=π3 ∴ minimum distance between such points =2y=2DΔxd=2DΔϕλd2π=21π36000×10-1010-32π=0.2mmTalk to our academic expert!

In an interference arrangement, similar to Young’s double slit experiment, the slits S1 and S2 are illuminated with coherent microwave sources, each of frequency 106 Hz. The sources are synchronized to have zero phase difference. The slits are separated by distance d = 150.0 m. The intensity is measured as a function of , where is defined as shown in the figure. If I0 is maximum intensity, then for
