The number of angular nodes in an orbital is determined by the azimuthal quantum number ($l$), and the total number of nodes is given by $(n - 1)$, where $n$ is the principal quantum number.

1. Angular Nodes: Given as 3. Since angular nodes = $l$, we have $l = 3$. An orbital with $l = 3$ corresponds to an f-orbital.
2. Total Nodes: Given as 3. Since total nodes = $n - 1$, we have $n - 1 = 3$, which implies $n = 4$.

Combining these, the orbital with $n = 4$ and $l = 3$ is the 4f orbital.
