Caculate the expectation value (r) for an electron in the ground state of the hydrogen atom. remember, the maximum of the radial ground state wavefunction, i'mar, is equal of the bohr radius. is the expectation value (r) larger, equal or smaller than i mar? give a brief explanation. b) (10 pts] using the expectation value (r )nim = 1/(aon) and the energy values for an electron in a bound state (nlm) of the hydrogen atom, show that the expectation values of the kinetic energy operator t and of the potential energy v are such that: 2(t)nim = -(v)nlm

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
