The radio signal itself, of course, is not an energy transformation - energy transformation means that energy is changed from one type to another. There is an energy transformation when the radio signal is created, and another one when it is absorbed.
The main energy-changes are as follows: Chemical (in the battery) to electrical Electrical to sound
In a radio, energy transfers through electromagnetic waves. The electrical signal from the radio station is converted into electromagnetic waves, which travel through space and are picked up by the radio's antenna, converting them back into sound waves that we can hear.
Electric energy to kitenic energy
A kerosene lantern involves the transformation of chemical energy stored in kerosene into light and heat energy through combustion.
Electrical energy is transformed into electromagnetic waves, which travel through the air to a receiver in the radio. The receiver then transforms these waves back into electrical signals, which drive the speakers to produce sound waves that we hear as music or speech.
