Suppose you like to listen to two different radio stations. the opera station broadcasts at 90.5 mhz and the rock and roll station broadcasts at 107.0 mh. s. which station's signal has waves with longer wavelenghts and which stations signal has station has waves with higher energy?

The "Opera" at 90.5 MHz has lower frequency, so its wavelength is longer.
Whichever station is transmitting with higher power has waves with higher energy.
Each photon of the transmission at 107.1 MHz carries more energy,because the energy of a photon is proportional to its frequency. But it's a mistake to think that the station at higher frequency haswaves with higher energy.

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.
