W What is the frequency of an electromagnetic wave that has a wavelength of
3.7 x 10-11 m in a vacuum? (The speed of light in a vacuum is 3.00 x 108
m/s.)

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.

The answer is true for your question.
