Are sound waves and electromagnetic waves radiation?

Answer 1

Broadly speaking, radiation is anything that spreads outward from a central source. In physics, the definition of radiation is constrained to energy that has been emitted from a source, is being transferred through a media, or is propagating through space. This energy can take on the form of particles or waves. Therefore, technically, both sound waves and electromagnetic waves are radiation. However, in practical usage, you would only use the term radiation when referring to electromagnetic waves or radioactive processes. The term, "sound radiation," is rarely, if ever, used.

Answer 2

Sound waves aren't a form of electromagnetic radiation.

Sound is a sequence of waves of pressure that propagates through compressible media such as air or water. It is perceptible by humans as frequencies from about 20 Hz to 20,000 Hz.

As a mechanical wave it is an oscillation of pressure transmitted through a solid, liquid, or gas.

Radio waves, microwaves, infrared waves, visible light, ultraviolet waves, x rays, and gamma rays are all forms or electromagnetic radiation.

Answer 3

No, but it is possible to hear their effects.

Answer 4

No, you cannot hear electromagnetic radiation because it does not actually move the air particles as it travels. (Which is why light can travel in a vacuum and sound can't.)

Answer 5

Visible light. The human eye is sensitive to frequencies between 400 and 790 terahertz.

Answer 6

The frequencies of electromagnetic waves that are visible are called "visible light". It's a small portion of the electromagnetic spectrum; most electromagnetic waves are NOT visible.

Answer 7

No
