Why do mobile phones emit radiation?

Mobile phones emit radiation because they use electromagnetic waves to communicate with cell towers. This radiation is in the form of radiofrequency (RF) waves, which are a type of non-ionizing radiation. The RF waves are generated by the phone's antenna and are used to transmit and receive signals to and from the cell towers. This allows the phone to make calls, send messages, and access the internet wirelessly. However, it is important to note that the level of radiation emitted by mobile phones is considered safe for human exposure, as it falls within the guidelines set by regulatory bodies.
