In an experiment, electrons are made to pass through a narrow slit of width `d` comparable to their de Broglie wavelength. They are detected on a screen at a distance `D` from the slit (see figure)`.
`

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 ).

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
The electron beam will be diffracted and the maxima is obtained at `y=0`. Also the distance between the first minima on both side will be greater than d.
