Lightning flashes and radio bursts arrive at different times due to propagation speed differences
the verdict
SUPPORTED
the evidence backs this
confidence 79/100
Electromagnetic emissions from lightning flashes travel as radio waves that experience frequency-dependent dispersion and propagation delays, causing different signal components to arrive at different times.
