A gas of helium atoms (each of mass 6.65×10−27kg) is at room temperature of 7.1°C. What is the de Broglie wavelength of the helium atoms that are moving at the root-mean-square speed?
Solved the probability of reflection R for a particle of mass m= 1.67 x 10-27kg and kinetic energy of Ekin = 0.4meV, which hits a rectangular barrier of height Vo=0.5meV. The width of the barrier is 1 nm. Personal note: I understand in this scenario is the Ekin < Vo, so I first start out trying to solve the tunnelling property T. The formula of which is as follows. VA'12 4x2 T = v[A12 4x2 + (1 + x2)2 sinh2(2aqo)...
2. (a) When a particle of mass 1.0 x 10-26 g in a one-dimensional box goes from the n=3 level to n=1 level, it emits a radiation with frequency 5.0 x 1014 Hz. Calculate the length of the box. (b) Suppose that an electron freely moves around inside of a three-dimensional rectangular box with dimensions of 0.4 nm (width), 0.4 nm (length), and 0.5 nm (height). Calculate the frequency of the radiation that the electron would absorb during its transition...
