... Louis de Broglie suggested in his dissertation that since light has both particle-like and wave-like properties, perhaps all matter might also have wave-like properties. He postulated that the wavelength of objects was given by λ = h/p, where where h is Planck’s constant, and p = mv is the momentum. ...

... The three views each show two nodal planes for three total: xy, xz, and yz. Thus, l must equal 3 (i.e., this is an f orbital). There are no spherical nodes present; thus, n = 3 + 1 = 4 (i.e., a 4f orbital). The orbital is not cylindrically symmetric about the z (or any) axis; thus m ≠ 0, but m could ...

... Let’s do an example. Consider a 1 eV electron incident on a barrier 5 eV high and 0.5 nm wide. 5 is “sort of considerably" bigger than 1, and 0.5 nm is long compared to a typical low-energy electron wavelength. Thus we can probably get away with using the simplified transmission equation. First, we ...

... Ex. Imagine a car’s fundamental quantum of energy corresponds to a speed of 10 km/hr. If the car has 7 quanta of energy, it will have a speed of 70 km/hr. If the car has 9 quanta of energy, it will have a speed of 90 km/hr. This shows that a car can only move in multiples of 10 km/hr (in this case). ...
