Cubic Conducting Cavity: For a cavity consisting of a conducting cube with sides of length L get 2 2 2 2 2 z y x n n n c Lf L + + = = where n x , n y , n z = all positive integers . This equation describes all possible wavelengths (or frequencies) of electromagnetic radiation in the cubical conducting cavity. We must count the number of allowed frequencies in the cavity. xaxis yaxis zaxis E B Direction of Propagation One Dimensional Conducting Box . 5 1 n = 1 n = 2 n = 3 yaxis zaxis xaxis O L L L...
