Q. The ratio of intensities of successive maxima in the diffraction pattern due to the single slit is
A) 1:4:9
B) 1:2:3
C) $1:\frac{4}{9\pi^{2}}:\frac{4}{25\pi^{2}}$
D) $1:\frac{4}{\pi^{2}}:\frac{9}{\pi^{2}}$
Explanation
(c) The ratio of intensities of successive maxima is
$1:\left( \frac{2}{3\pi} \right)^{2}:\left( \frac{2}{5\pi} \right)^{2}:\left( \frac{2}{7\pi} \right)^{2}$
$= 1:\frac{4}{9\pi^{2}}:\frac{4}{25\pi^{2}}$
