In an experiment, electrons are made to pass through a narrow slit of width d comparable to their de-Brogile wavelength. They are detected on a screen at a distance D from the slit.

Which of the following graphs can be expected to represent the number of electrons N detected as a function of the detector position y(y = 0 corresponds to the middle of the slit)?

Options

A.
B.
C.
D.

Answer

A

Explanation

As size of slit iscomparable to wavelength so electron beam will be diffracted. So we observer central amxima flanked by number of secondary maxima.
