Do mobile phones use radio waves or microwaves?
First, radio waves and microwaves are similar in nature, but I’ll elaborate on that later. Microwaves are like visible light, but with a lot lower frequency (even lower than infrared). Anything between 300 MHz and 300,000 MHz is considered to be a microwave. A typical frequency for phones typically use the 900 MHz and 1800 MHz band (may differ slightly depending on location and phone type). This frequency range is clearly within the microwave portion of the spectrum. Now, on to what I mentioned in the first portion. Radio waves and microwaves are a type of electromagnetic radiation. Electromagnetic radiation is everywhere, and is the general way to describe what radio waves are, what microwaves are, what light is, what x-rays are, and what gamma rays are. The only difference between all of these types is the amount of energy they possess. In the way that I have listed them above, they start with low energy and increase to the highest. The lower the frequency, the lower the energy of th
