[SI-LIST] : Chassis hole opening and frequencies

As I recall, there is a relationship between a hole in a chassis and the
frequencies that can pass through that opening. I recall that the longest
dimension of the hole defines the wavelength, or quarter wavelength, or
something, of the lowest frequency than can conveniently enter or escape
through the opening.

Can anyone give me the correct relationship?

Thanks.

And Happy New Year to All...........
