Microwave signals are more focused, and therefore less susceptible to interference than radio waves. Microwave signals are used in a variety of applications. Some cell phone networks and wireless devices, such as Bluetooth, use low frequency or longer length microwave signals, and these signals are also utilized by the primary television broadcast stations and wireless internet connection.
There are microwave signals in the cables that deliver TV and high-speed internet access. In microwave cooking, the radio waves infiltrate the food, and the water and fat molecules are distributed evenly throughout the food.
The entire heating process is different because you are instigating atoms, as opposed to conducting heat. Microwaves are shorter than radio currents, with wavelengths assessed in centimeters. We use microwaves for cooking food, transmit information, and radar that helps predict the weather.
