Question 338: Waves Optics

Question

In the experiment of diffraction due to a single slit, if the slit width is decreased, the width of the central maximum

Accepted Answer

Width of the central maxima $$=W=\frac{\lambda 	heta}{d}$$
Thus, the slit width is inversely proportional to the width of the central maximum.
Hence, when the slit width is decreased, the width of the central maxima increases.

Answer

becomes zero.

Answer

does not change.

Answer

increases.

Answer

decreases.
