Question

Formula to find kinetic energy of an electron when wavelength is given

Answer 1

What is the De Broglie wavelength of an electron given it has a kinetic energy of 1 eV? You are given the mass of an electron is 9.11x10^-31 kg and Planck's constant is 6.63x10^-34. We know the value of Planck's constant h and so to calculate the wavelength all we need is the momentum, which is equal to mv.
