Cell Phones

Something I have always wondered is the way in which a cell phone works. Everyone has them in today's world so now I need an explanation to how they work in a physics sense.

Image result for cell phone

From what I understand, when someone talks into the phone, their voice is converted into a signal that is transmitted through waves and then back into sound on the other end. Essentially it sounds like a two way radio. The signal is a type of radio wave that in the end can be dangerous to humans resulting in various health issues in the long run. Are cell phones really worth it if we are exposed to even more radiation that we need to be?

Until next time,
