SUMMARY
The discussion focuses on calculating the wavelength of an electron with a kinetic energy of 2.00 eV. The incorrect formula used was E=h(c/n), where n represents the wavelength. The correct approach involves using the de Broglie wavelength formula, λ = h/p, where p is the momentum of the electron. The momentum can be derived from the kinetic energy using the relation p = √(2mK), where K is the kinetic energy and m is the mass of the electron.
