An electron and a proton each have a thermal kinetic energy of 3kBT/2. Calculate the de Broglie wavelength of each particle at a temperature of 2170 K. (kB is Boltzmann's constant, 1.38×10-23 J/K. The mass of the electron is 9.11×10-31 kg and the mass of the proton is 1.67×10-27 kg.)
good luck, i was thinking of taking quantum physics
