PROBLEM TO BE SOLVED

Calculate the wavelength, a of an electron with a kinetic energy of kТ at 300 K. Boltzmann constant k = 1.380658 x 10-23 J K-1

Answer 1

Kinetic energy = KT = 1.380668 x 105 x 300 JK K = 4.14 1974 X10 21 J In other words, Energy = he where, ha 6.626810 34 IS c= 2.99792458x108 ms = 4:141974 x 10-21 = 6.62.6 x10334 x 2.99292458 X108 ws msl a = 6.626 X 10 34 x 2.9 s ^2way - y.141974 x 10-21 wavelength, => x = 4.79584 x 105 m
