Can anyone give me a picture of what the above terms mean..I know the mathematical meaning like
But i want to know like how and what exactly is a radial node and an angular node ! The node of an S sub shell is easy but where are the nodes in the P and d Sub shell ? And please explain what radial node and angular node mean..Thanks !

Nodes are typically considered where the solution is stationary at 0. For radial nodes, f(R)=0 for all angles. They look circular in the picture above. For angular nodes f(someAngle)=0 for all R. They look like the slices.

You'll also find that all orbitals where n > l have radial nodes (i.e. every orbital except the first s,p,d and f orbitals), and every orbital where n > 1 (i.e. nons orbitals) have angular nodes.

What is a radial Node ? What is an Angular Node ?
I know the technical defination of nadoes but i need a pictorial defination..So that i can understand how it looks !

Think of the difference between radial nodes and angular nodes as being like looking at a bullseye vs. a 4leaf clover. The nodes are the spaces between the circles in the case of the bullseye (radial node) and the spaces between the leaves in the case of the 4leaf clover (angular node).
