Give at least one useful application for each type of wave.

Explanation / Answer

radio waves, microwaves, infrared, visible light, ultraviolet light, X-rays, gamma rays

The lowest on the electromagnetic spectrum are the radio frequencies. They can be very low (in the audio range) to very high in the microwaves. Some like to classify microwaves as a separate type of electromagnetic class. Included in these ranges are radio stations, television and cell phone frequencies for example. Radar uses microwaves.

Next is the infrared.

After that is visible light in the colors of the rainbow (I'll spare listing them in order).

After that are, in this order, ultraviolet rays, x-rays and gamma rays, and gamma rays are very high energy waves found in space from stellar phenomenon.

They "used" to classify cosmic rays above the gamma rays, but they were then found to be in fact particles whereas electromagnetic energy is not a particle.
