s: sharp
p: principal
d: diffuse
f: fundamental
Physicists who were studying the electromagentic spectrum tried to describe the emission lines as they corrolated with energy states involved. They described the emission lines as sharp, principal, diffuse, and fundamental.
In chemistry, the s, p, d, and f are letters associated with atomic orbitals. These letter designations are used for electron configuration of different elements on the Periodic Table.
The question is ambiguous but s p d and f are the types of electron orbital.
