How to solve this question with a detailed solution?
[5 marks] Calculate the de Broglie wavelengths for the following three electron energies: 50 eV, 50 KeV, and 50 MeV. Use both the classical calculation and the relativistic calculation and compare the two answers. For the classical calculation, you can use the formula λ = h/p, where λ is the de Broglie wavelength, h is Planck's constant, and p is the momentum. To obtain the momentum for the classical calculation, use the equation p = √(2mE), where m is the mass of the electron and E is the energy.
For the relativistic calculation, start with the two equations E^2 = (pc)^2 + (mc^2)^2 and E = K + mc^2, where E is the total energy, K is the kinetic energy, and mc^2 is the rest energy of the electron (511 KeV).
