<u>Answer</u>:
Cell phones contain rechargeable batteries that transform chemical energy into electrical energy. When using your cell phone, electrical energy is first transformed into <u>Electromagnetic waves </u>that are transmitted through the air.
<u>Explanation</u>:
When chemical energy is converted into electrical energy in cell phones, then this electrical energy firstly transformed or converted into electromagnetic waves which travels through air. Then this electromagnetic wave is converted into sound energy due to which users are able to listen audio, music, movies etc on their mobile phones.
