Which statement about the wave function for a single electron is NOT correct? 1- Louis de Broglie postulated that the wavelength of an electron is given in terms of Planck's constant and its momentum, λ = h / p. 2- A French graduate student named Louis de Broglie first had the idea that an electron should be described as a wave. 3-The amplitude of a wave function at a particular point in space equals the probability density of finding the...

Learning Goal: To understand de Broglie waves and the calculation of wave properties. In 1924, Louis de Broglie postulated that particles such as electrons and protons might exhibit wavelike properties. His thinking was guided by the notion that light has both wave and particle characteristics, so he postulated that particles such as electrons and protons would obey the same wavelength-momentum relation as that obeyed by light: λ=h/p, where λ is the wavelength, p the momentum, and h Planck's constant. Part...

The ionization potential of a hydrogen atom is 13.6 eV. How does this compare to the energy of a typical particle at the recombination epoch, when the temperature of the universe was 3000 K. How does that compare to the energy of photons at the peak of the Planck function at that time? What can you conclude from these comparisons?
