Show that ψ2 and ψ3 for the one-dimensional particle in a box are orthogonal.
Find the lowest energy of an electron confined to move in a three dimensional potential box of length 0.48 Å.
The first four Hermite polynomials of the quantum oscillator areH0 = 1, H1 = 2x, H2 = 4x2 − 2, H3 = 8x3 − 12x.
Let p(x) = 12x3 − 8x2 − 12x + 7. Using the basis H = {H0, H1, H2, H3}, find the coordinate vector ofp relative to H. That is, find [p]H.
