In Young's double slit experiment, the ratio of intensities at two points on a screen when waves from the two slits have a path difference of zero and $\frac{λ}{4}$ is $[cos 0^{\circ} = sin 9 0^{\circ} = 1, sin 0^{\circ} = cos 9 0^{\circ} = 0]$

Answer:

Solution:

$I = 4 I_{0} cos^{2} \frac{ϕ}{2}$ $ϕ = \frac{2 π}{λ} \times \frac{λ}{4} = \frac{π}{2}$ $\frac{ϕ}{2} = \frac{π}{4}$ $\frac{1}{I _{0}} = 4 cos^{2} \frac{π}{4} = \frac{4}{2} = 2 : 1$
