 Electromagnetic radiation includes radio waves.

Lightning strikes, lightning storms, and natural phenomena, as well as man-made sources like radio transmitters, all contribute to the ambient electromagnetic field.

By traveling through space and the atmosphere of Earth, electromagnetic waves from the sun are transformed into "radio waves" before finally reaching the surface.

AM radios, FM radios, and shortwave radios are the three main categories of radios.

Radio is shorthand for "radio receiver/transmitter," which describes the function of the gadget. However, this definition is overly broad and does not adequately describe the products available today. It's important to know how many different kinds of radios there are and what each one is capable of if you want to know what's out there.

A radio can be classified as either a communications radio, a broadcast radio, or a wireless radio. Walkie-talkies and CB radios fall under the first category, while FM and AM radios and wireless gadgets like WiFi routers and Bluetooth headphones make up the second.

Antenna modulation (AM) radios and frequency modulation (FM) radios are the two primary radio types.

In contrast to FM radios, which employ frequency modulation, AM radios use amplitude, or the voltage differential between the two ends of the transmission. What this means is that the frequency of every sound wave emitted by the transmitter is same (or "wavelength").

On the other hand, FM radio is a more complex form of radio that calls for more expertise to operate.

It does this by amplitude modulation, which involves sending a signal to the receiver at a sufficiently high amplitude for the signal's frequency to be heard above any interference.

Numerous varieties of radios are available, each with its own set of pros and cons. 

You can see that each one has a unique set of uses depending on the content you're interested in hearing or learning more about.

It's important to know that there are three distinct varieties of radio. AM radio, FM radio, and shortwave are the three.

AM is by far the most popular and commonly used of the two. 

FM, the second, is more up-to-date. It's more sensitive to the signal and can receive it from farther away, much like AM. Shortwave is the third option, and it's frequently utilized by those who can't get a good signal with the other two.
