name a device which changes chemical energy into light energy and electric energy into heat energy, heat energy into electric energy, electric energy into magnetic energy, light energy into electric energy, electric energy into sound energy and light energy into chemical energy​

Answer 1

Answer:

There is a device that uses electrical energy to power an electromagnet that is inside a permanent magnet. The electromagnet is attached to one side of a cone made of various materials. The other side of the cone has a flexible material that attaches the cone to a rigid cage. As different pulses of electricity are passed through the electromagnet the cone vibrates at various frequencies thereby creating sound energy. This device is known as a speaker.
