It's a quantum mechanics question.

Step 1

The relation between the Cartesian and spherical coordinates is given as,

Step 2

Here *θ* is the polar angle and *φ* is the azimuthal angle.

Use the spherical polar coordinates to rewrite the wave function *ψ* in terms of *r*, *θ*, *φ *as,

Step 3

Here *Ylm *represents spherical harmonics and *Rnl *(*r*) represents the radial part of the wave function.

a)

The operator...
