Problem

In a Young's double slit experiment, the intensity at a point is

\left(\frac{1}{4}\right)^{\text{th}}

of the maximum intensity, the minimum distance of the point from the central maximum is ______

\mu\text{m}

. (Given :

\lambda = 600 \text{ nm}

d = 1.0 \text{ mm}

D = 1.0 \text{ m}

)
