Frightening Fact Number 1: WiFi is radiation!

But what kind of radiation?

Wi-Fi uses a frequency of 2.4Ghz. These are microwaves, down below infra-red on this diagram of the electromagnetic spectrum.

All of these different frequencies are radiation. Some are dangerous. Radiation on the high-frequency and short-wavelength end of the electromagnetic spectrum is called "ionising" — high frequency ultraviolet, X-rays, and gamma rays—are ionizing because photons at this end of the spectrum have high energy and can do a lot of damage. That's why we put sun cream on.

Visible light radiation has less energy, infra-red even less and microwaves and radio waves even less.

We wouldn't really worry about putting another light on. And yet microwaves have a lot less energy than visible light.

A meeting with Nasrudin

One day people came across Nasruddin pouring the last bit of his yoghurt into the lake.
"Nasruddin , what are you doing? "someone asked.
"I am turning the lake into yoghurt," Nasruddin replied.
 "How can a little bit of yoghurt do anything to all this water?" the man asked.
 "I know, I know, it's not supposed to," Nasruddin replied," but what if it did...?"
