Electrons are accelerated through a potential difference of $\mathrm{V}_{0} \mathrm{kV}$. The de Broglie wavelength (in $\mathrm{m}$ ) of the electrons is (a) $\frac{\mathrm{h}}{\sqrt{1000 \mathrm{meV}_{0}}}$ (b) $\frac{\mathrm{h}}{\sqrt{2000 \mathrm{meV}_{0}}}$ (c) $\frac{\mathrm{h}}{\sqrt{\mathrm{meV}_{0}}}$ (d) $\frac{\mathrm{h}}{2 \mathrm{meV}_{0}}$
What is the de Broglie wavelength of a beam of electrons having kinetic energy K = 100 eV Question 1 options: 12 pm 120 pm 1.2 nm 12 nm 120 nm The electron volt is a unit of Question 2 options: momentum. voltage. energy. charge. None of the above. If a beam of monoenergetic electrons with an energy of 78 eV are incident upon a crystal spacing (slit size) of 0.215 nm, what is the smallest angle for which we will see constructive interference? Question 3 options: 0 degrees 20 degrees 40 degrees 60 degrees 80 degrees The potential energy associated with a Simple Harmonic Oscillator is given by Question 4 options: a square wave. a step-function. a parabola. a hyperbola.
