"Physics related to cellphone"

 Physics involves the study of matter and motion through space time, as well as energy and force. So broadly anything has to do with physics. Cellphones are created for us to be able to communicate easily with others.The device uses a microphone in the handset to convert the sound waves to electrical signals, which are sent through the telephone network to the other phone, where they are converted back to sound waves by an earphone in the handset.


If you take a cell phone apart, you find that it contains just a few individual parts, such as, an antenna, a liquid crystal display (LCD), a keyboard, a microphone, a speaker, and a battery. Inside the phone there is a circuit board. The circuit board is the heart of the system. Your journey through the computer chips on the circuit board would consist of three rooms. And these circuit board one of many evidences how we can say that Physics is being applied to Cellphones.
