In a radio you have the conversion of radio wave energy to sound wave energy.
what is the transformation of energy in battery-operated radio
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.
Because it is making sound. A radio also gives off heat energy that is wasted
A radio , when operating may give off a little' heat'. This is wasted energy. We don't want heat from a radio , we want 'sound'.
A radio produces sound, and therefore sound energy. The radio waves, however, are electromagnetic energy, not sound. The function of a radio is to convert that electromagnetic energy into sound energy.

I was listening to my radio.
what is the transformation of energy in battery-operated radio
yes,because radio is an example of sound energy...
what is the transformation of energy in battery-operated radio
The "radio" is named as such to reflect the type of energy used to cause the radio instrument to operate. That being "Radiant Energy."
Yes. Radios use radio waves which are radiant energy.
A radio receiver transforms electrical energy to acoustic energy
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.
I listen to the radio every night!
yes. because you have to plug in the radio which is electrical and then when you turn on the radio it produces sound. even if it's a battery powered radio, the battery stores energy in the form of chemical energy, but delivers it as electrical energy, so even in that radio, the radio is converting electrical energy to sound energy when you turn on the radio. What about an old-fashioned "crystal set" that has no battery and doesn't plug into the wall ? Even that one converts electrical energy into sound. The only electrical energy it ever gets is what it picks out of the air that got transmitted from the radio station. That's very very little energy, which is why the sound from a crystal set is always so weak.
