No, the GP got it right. High-frequency = short wavelengths, which can squeeze through small gaps in metal more easily than long wavelengths. (Visible light is an extreme example of this.)
- version_five 4y agoRight, I wasn't thinking about it this way, and I probably wouldn't for the purpose of blocking EM. In principle, low frequency penetrates better but as you say high frequency can get into things more (but doesn't necessarily). Of course I didn't actually look up what frequencies we're talking about- low and high can mean a lot of different things
