Explanation:
Detailed explanation-1: -Wi-Fi uses radio waves to transmit information between your device and a router via frequencies. Two radio-wave frequencies can be used, depending on the amount of data being sent: 2.4 gigahertz and 5 gigahertz.
Detailed explanation-2: -Wi-Fi transmits data using microwaves, which are high-energy radio waves. Wi-Fi is more complicated than FM radio, but the basic underlying technology is the same. They both encode information into radio waves, which are received and decoded.
Detailed explanation-3: -Technologies like 802.11 standards (a.k.a. WiFi) use amplitude modulation while other radio technologies continue to use digitally modulated frequency modulation.
