"""General rule of thumb is that the opening in a Faraday cage should be smaller than 1/10th of the wavelength that should be blocked. For example, in order to block EM fields with frequencies of 10 GHz and lower, the hole size of the Faraday cage should be smaller than 3 mm."""
wavelength of red in inches: 2.46063e-5
wavelength of 2.4ghz in inches: 4.25
wavelength of xrays in inches: 7.87402e-7 (upper end)
You could easily see through a 4.25 mesh, that's almost chain link
you could not see through a 2.4e-5 mesh, that's call fabric, unless you can see through clothes in which case I'm not going near you. xrays can see through that :)
