Q:

What does a sound source of high energy emit?

Quick Answer

A sound source of high energy emits waves, just like any other source of energy. Waves are defined only by their frequency and wavelength. High frequency means high energy and short wavelength means high energy. Sound has a long wavelength, so it has low energy in the electromagnetic spectrum.

Full Answer

The lowest-energy wavelength is radio, which corresponds to sound. Then, there's microwave energy. Next, there's infrared energy. The visible wavelength follows this, with red, orange, yellow, green, blue, and indigo. The blue and indigo of the visible spectrum stretches into the near ultraviolet, which has a wavelength too short for humans to see. After the ultraviolet comes X-rays and then gamma-rays, which are the highest forms of energy anything can emit.
