Q211 / 225 · JEE Main 2005 · Physics

If $\mathrm{I}_0$ is the intensity of the principal maximum in the single slit diffraction pattern, then what will be its intensity when the slit width is doubled?

A
$2\mathrm{I}_0$
B
$4\mathrm{I}_0$
Correct answer
C
$\mathrm{I}_0$
D
$\mathrm{I}_0/2$

Solution

Maximum intensity is independent of slit width

Hence, the correct answer is option: 'C'.
