The intensity at the maximum in a Young’s double slit experiment is $I_0$. Distance between two slits is $d = 5 \lambda$, where $\lambda$ is the wavelength of light used in the experiment. What will be the intensity in front of one of the slits on the screen placed at a distance $D = 10 \;d$ ?

Question

( A ) $\frac{3}{4}I_0$
( B ) $I_0$
( C ) $\frac{I_0}{4}$
( D ) $\frac{I_0}{2}$
