Need help ASAP Will mark BRAINLIST and thanks only for correct answers

1.What is the correct way a cell phone call goes out?

-The phone call goes out, transmits through microwaves, then moves to the central hub. Then the signals go to the nearest tower to the receiver of the call.

-long wavelength

3.what types of waves do cell phones use?

1. The phone call goes out, transmits through radio waves, then moves to the central hub. Then the signals go to the nearest tower to the receiver of the call.

2. long wavelength

3. radio waves

Explanation:

1. A cell phone call is works basically as a two-way radio, consisting of a radio transmitter and a radio receiver. When you dial a call to a friend on your cell phone, your phone converts your voice into an electrical signal, which is then transmitted through radio waves. The radio waves then moves to the central hub. Then the signals go to the nearest tower. The network of cell towers then relays the radio wave to your friend’s cell phone, which converts it to an electrical signal and then back to sound again.

2. AM means amplitude modulation. In AM frequencies, sound signals are modulated by changing the amplitude or maximum height of radio waves. AM frequencies use longer wavelength radio waves than FM frequencies. Because of their longer wavelengths, AM waves reflect off a layer of the upper atmosphere called the ionosphere, and thus travel over longer distances than FM waves.

3. Cell phones use radio waves to communicate.

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.
