Is there a way to harness the energy of electromagnetic feedback?
Indeed, without feedback we would not have oscillators in electronic circuits.
Is electromagnetic energy visible?
As visible light, yes. As ultraviolet causing fluoresence in some natural minerals and in electric flourescent lights, yes. Otherwise, no, but we can pick up radio/television/radar frequencies on electronic equipment, we can feel heat, and we can detect infra-red, and ultraviolet with electronic sensors, and detect X-rays with photographic film. The following answer really addresses static electricity and electrical discharge. Yes. Electromagnetic energy is visible if you look hard enough for it. When you roll over in your bed at night and notice blue light streaks shooting up the blanket, you have witnessed electromagnetic energy. You can see signs of it in your hair after rubbing a blanket or balloon against it. "Frizz" is just electromagnetic energy making your hair attract to nearby particles (most likely nitrogen) with the opposite charge.
Is it true that the transmitter of a radio station combines an electronic signal with a sound waves?
No. The transmitter of a radio station emits an electromagnetic signal that has been modified by sound waves that were converted into an electronic signal.
What is electromagnetic pluse?
An electromagnetic pulse is a very powerful but very brief burst of electromagnetic noise; nuclear explosions in the atmosphere produce magnetic pulses. These can overload electronic equipment, by inducing powerful, brief currents. They are essentially like ridiculously powerful radio broadcasts that destroy the radios which receive them.
What is an electronic wave?
One way to look at electronic radiation might be to see it as the electromagnetic energy radiated by electronic equipment as a function of their operating circuits. Current technology is replete with myriads of complex electronic devices, and these all emit low power electromagnetic radiation that is generated within their circuitry. That is the nature of electronics. We get that radiation even though we might not want or need it. From this perspective, we can differentiate that kind of radiation from the kind we see that is intentionally generated for transmission to facilitate wireless communication between devices.

What are oscillators used for?
Signal generators: reference (tuning equipment) source - such as electronic keyboards beat frequencies - as in a superheterodyne radio

What does a synthesiser do in music?
With the help of synthesiser, the sound of the existing instruments could be emulated. It also uses electronic oscillators to create an artificial sound.
