Question

Write a schematic diagram of a single slit diffraction experiment and write condition for minima and secondary maxima.

Answer 1

$\underset{–}{\text{Condition for minima}}$

$dsin\theta =n\lambda ,wheren=1,2,\lambda ,\underset{–}{}$

$\underset{–}{\text{Condition for Secondary minima}}$

$dsin\theta =(2n+1)\frac{\lambda }{2},wheren=1,2,3,\underset{–}{}$
