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 $\frac{a _{1}}{a _{2}} = (\frac{1}{9})^{1/2} = \frac{1}{3} \frac{I _{minima}}{I _{maxima}} = \frac{( a _{1} - a _{2} ) ^{2}}{( a _{1} + a _{2} ) ^{2}} = \frac{1}{4}$
