If shorter waves have more energy than longer waves and 5g is actually the same as „light“ but with *longer* wavelengths: How can 5g be harmfull?

Light, 5g are both actually electromagnetic radiation. 5G should contain less energy (it‘s mmwave instead of nmwave). So why could it be harmfull?

Low frequency radiation can still be harmful if the intensity is sufficiently high. High frequency radiation is like a series of bullets that smash the electrons off your atoms, causing them to have undesired chemical reactions. Low frequency radiation is like a gentle sloshing wave that tries to pull charges back and forth. If it intensity is strong enough, it will pull polar molecules or ions back and forth quite dramatically, which heats up the material. This is how a microwave oven works, and can in principle be dangerous.

So from a pure theoretical basis alone, you can't argue that low-frequency radiation is inherently safe in all situations (although this isn't true for water either). It's a question of quantity, not the fundamental nature of the wave. The relevant question is whether the real 5G systems have anything close to the intensity required to cook a human form the inside - and they don't.
