Dear Student,

An orbital wave function is written as product of Radial function and Angular function. The Radial wave function depends upon n and l quantum number, and Angular wave function depends upon l and m_l quantum number.

ψ = R(r).A(θ,Φ)

Radial function depicts the size of the orbital and angular function determines the orientation of lobes of orbital. Node is a region where, probability of finding an electron is zero. So, Radial node is the point where,

ψ = A(θ,Φ) for all R and it can be shown as

and Angular node is the point where,

ψ = R(r) for all A and it can be shown as

Note: The points which meet the axis are nodal points.

Hope this information is helpful.
