Question 318: Wave Optics

Question

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

Accepted Answer

The slit width has no effect on the intensity of the principal maximum in the single-slit diffraction pattern.
$$	herefore$$ The intensity will be same, $$\mathrm{I}_0$$.

Answer

$$\frac{\mathrm{I}_0}{2}$$

Answer

$$\mathrm{I}_0$$

Answer

$$4 \mathrm{I}_0$$

Answer

$$2 \mathrm{I}_0$$
