::NOTE: Please ignore the linearly interpolated "13 C" above. It turns out ''n'' for radio waves is a highly nonlinear function of temperature. Plus the 1/Δ''n'' dependence -- where Δ''n'' changes by a factor of 7 or 8 -- makes the nonlinearity even worse. --[[User:Redbelly98|Redbelly98]] ([[User talk:Redbelly98|talk]]) 01:05, 7 August 2018 (UTC) | ::NOTE: Please ignore the linearly interpolated "13 C" above.

::Ehh... I see your point, but I'm not sure I'm *really* convinced. In my mind, a Gamma Ray Spectrometer is specialized equipment. People don't normally have them in their house or car. Radios are (or, at least, *were*) very common. But you're right, it says specialized instrument, not "rare" instrument. I'm not changing the explanation, just wanted to point out for those geeky enough to read the comments that for normal people, *detecting* the radio wave output lightning is doable without buying extra equipment one doesn't normally have in the home. Detecting the difference between the flash and the static on the radio is where it gets impractical. [[Special:Contributions/172.68.54.64|172.68.54.64]] 15:01, 6 August 2018 (UTC) (newbie) | ::Ehh...

I always thought it was 1 second per mile. I didn't know about the 'divide by 5" part.

:Storms just became 5 times more scary for you :) [[Special:Contributions/188.114.103.95|188.114.103.95]] 12:12, 6 August 2018 (UTC) | :Storms just became 5 times more scary for you :) [[Special:Contributions/188.114.103.95|188.114.103.95]] 12:12, 6 August 2018 (UTC) | ||
