Final answer:
The radial wave function represents the radial behavior of the electron, while the angular wave function describes the orientation and shape of the electron orbital.
Step-by-step explanation:
The radial wave function and angular wave function are components of the wave function in quantum mechanics.
The radial wave function, denoted by R, depends only on the radial coordinate r and represents the probability density of finding an electron at a certain distance from the nucleus. It is responsible for the radial behavior of the electron.
The angular wave function, denoted as φ (phi), depends on the polar angle θ (theta) and azimuthal angle φ (phi). It describes the orientation and shape of the electron orbital.
