A question about the light spectrum

[QUOTE="sangho, post: 5485491, member: 595405"] For any given number(length), say L, is always there an electromagnetic wave with the wavelength L ? As I know, the source of electromagnetic wave is the energy emission of electrons changing it's quantum state in an atom. But there are at most about 120 atoms there, and the quantum numbers are, mathematically saying, countable. So I think the electromagnetic spectrum is not filled with all numbers in the axis.
