$I=I_0{\left(\frac{\sin \left(\alpha \right)}{\alpha }\right)}^2$and$\alpha =0,\frac{3\pi }{2},\frac{5\pi }{2}, \dots \dots \dots$, for maxima

The ratio of Intensities of successive maxima is

$1\mathrm{ }:{\left(\frac{2}{3\mathrm{\pi }}\right)}^2\mathrm{ }:{\left(\frac{2}{5\mathrm{\pi }}\right)}^2$or$1\mathrm{ }:\mathrm{ }\frac{4}{9{\mathrm{\pi }}^2}\mathrm{ }:\frac{4}{25{\mathrm{\pi }}^2}$
