In an experiment, electrons pass through a narrow slit of width ‘ d ’. They are detected on a screen at a distance ‘ D ’. Which graph correctly represents the number of electrons N detected as a function of the detector position y (y = 0 corresponds to the middle of the slit)?

Solution & Step-by-step Explanation

Since electrons exhibit wave properties, they undergo diffraction when passing through a slit comparable to their wavelength. This results in a typical diffraction pattern characterized by a central maximum and smaller intensity secondary maxima on either side.

Try it yourself before checking the explanation above.
