The ratio of intensities at two points P and Q on the screen in a Young's double slit experiment where phase difference between two waves of same amplitude are $\dfrac\pi3$ and $\dfrac\pi2$, respectively are
Answer: (D) $3:2$
$I\propto\cos^2\dfrac\phi2$: $\dfrac{\cos^2 30^\circ}{\cos^245^\circ}=\dfrac{3/4}{1/2}=3:2$.
