This is a little bit late, but in 2020, people have started to think that 5G (5 gigahertz) is killing us, but no. Your microwave operates between 300Mhz (megahertz) and 300Ghz (Gigahertz). People bring up the misconceptions that your microwave operates on 2.45Ghz, which is true, but also false. Your microwave can operate on 2.4GHz, but it wont do anything on such a low frequency. You need at least more than even 10GHz to even do something and 10 or 20 might also be nothing.
People say that:

“Oh well if your microwave operates on 2.45 gigahertz then 5 gigahertz will be very dangerous”.
REMEMBER: Wavelength is the horizontal length of one cycle of a periodic wave. It is also the horizontal distance between two successive crests, two successive troughs, or any two successive equivalent points on the wave. Frequency is the number of cycles per unit of time. The unit of frequency is a hertz (Hz).
Your microwave operates in wavelength between 300Mhz (megahertz) and 300Ghz (Gigahertz). The frequency of a microwave is 2.45 GHz. Got it? If not, read the simplification below. If you did, then scroll down after the simplification.
Simplification:
Wavelength is the type of wave that gets produced, specifically how high or low it is, example:

Frequency is how many times the wave is repeated, in hertz. Example:

Now you understand that a microwave is the danger and not the cell towers.
A microwave is designed to use microwaves to heat up food. Cell towers are designed so that you can have a wifi signal anywhere. They also have strict regulations to make sure that they are safe to use.
