Chapter 38, Problem 13A

To determine

Whether the diffraction of the electron beam support particle model or wave model of the electrons.

Explanation of Solution

Introduction:

The diffraction is the phenomenon in which the wave is bends around the small opening. The bending of the wave occurs due to the wave nature of the particles.

When the electron beam passes from the small opening that has the dimension nearly same as the wavelength of the electron beam bends around the small opening. The electron beam bends around the small opening. So, the electron beam behaves like a wave and supports the wave nature.

Conclusion:

The electron beam supports the wave model of the electrons because the electron beam beans around the small opening.
