PhysicsEasysingle choice

In Young's double slit experiment if the slit widths are in the ratio $1 : 9$ . The ratio of the intensity at minima to that at maxima will be

Options:

Answer:

Solution:

amplitude of the superimposing waves are

$\frac{a_{1}}{a_{2}} = {(\frac{1}{9})}^{\frac{1}{2}} = \frac{1}{3}$

$\frac{I_{m i n i m a}}{I_{m a x i m a}} = \frac{{(a_{1} - a_{2})}^{2}}{{(a_{1} + a_{2})}^{2}} = \frac{1}{4}$
