And neither of us can say it safe because as she pointed out there are enough studently to conclude that it’s safe.
c=lambda*f The wavelength of a red led is ~630nm so the frequency is ~480 THz. The energy of a photon is E=hf so proportional to the frequency. Therefore a red LED photon has approximately 20,000 times the energy of a 25 GHz 5G photon.
Admittedly I only have a high-school level knowledge of this, but my understanding is that (as the parent said) higher frequency = higher energy = lower wavelength. Hence visible light has more energy than any sort of microwave.
Did you mean the "length of the wave" instead of the "energy of the wavelength"? In that case we all agree.
I am using amplitude to describe the energy of a wave, you are using frequency.
EDIT: To expand on this further, you are materialists and think light is a particle, a photon. But light is not a particle, it is a wave and it always is a wave, until we measure it. Objectively it is a wave (a probability), subjectively it is a particle (a certainty).
What you are measuring is what you measure, so you cannot see the effects of what you are not measuring.
Because this radiation is non-ionizing you think it is harmless. That is your folly and not mine.
Because you think the energy of the wave lay only in the photon means you can see the energy of the wavelength.
It's more complicated. Anyway, when the light colide with your skin it counts like a "measurement". Most of the times, the light colides with an electron of your skin and the energy that the electron get's is the same energy that it would get in the photoelectric effect. https://en.wikipedia.org/wiki/Photoelectric_effect
> Is it's energy in the frequency or the amplitude?
Both. You can calculate the energy using the amplitude, and that energy determines how many photons will you count in a photoelectric experiment.
The wavelength determines the energy of each photon. The amplitudes determines the total amount of energy in all photons.
> Because this radiation is non-ionizing you think it is harmless.
Note that there are two ways in which light can be dangerous, let's call the "cancer" and "cooking".
As far as we know, non-ionizing radiation does not cause cancer.
You can cook something/someone using non-ionizing radiation but the power of the 5G antenas in not enough where people can go.
