The main difference between the frequencies used by Wi-Fi and microwave ovens lies in their respective ranges within the electromagnetic spectrum.
Wi-Fi operates within the radio frequency range, specifically in the 2.4 GHz and 5 GHz frequency bands. These frequencies are relatively low and are well-suited for wireless communication over short distances. Wi-Fi signals are used to transmit data between devices such as computers, smartphones, and routers.
Microwave ovens, on the other hand, utilize microwave frequencies in the range of 2.45 GHz. This frequency is also within the radio frequency spectrum but is specifically chosen for its ability to interact with water molecules, resulting in the heating effect that cooks food. Microwaves in this frequency range cause water molecules to vibrate rapidly, generating heat that cooks the food placed in the oven.
In summary, while both Wi-Fi and microwave ovens operate within the radio frequency range, they utilize different frequencies. Wi-Fi operates at 2.4 GHz and 5 GHz for wireless communication, while microwave ovens use 2.45 GHz specifically to heat food by interacting with water molecules.
