802.11 b/g channel wavelengths

(Writing this so that I can refer back to it, rather than keep having to look it up. Channels are 1-14, with the first row being channel 1. Consider these rough numbers; I didn't pay much attention to sigfigs, aside from using nine digits of c and four of the channel frequency as documented here. I also didn't use a bignum library, so IEEE754 floating point errors might be an issue; Depends on Perl's default floating-point implementation.)
