(a)
Interpretation:
The velocity of electron required for an electron diffraction experiment if the wavelength is
Concept Introduction:
de Broglie established a relation for particles of matter that they also can behave as a wave and has a wavelength. The wavelength of the particle is inversely proportional to its mass. The smaller the mass, the larger its wavelength.
The expression given by the de Broglie is as follows:
Here,
The expression to calculate the root-mean-square speed of particle is as follows:
Here,
