*******************
The solar energy emitted or traveling from the sun is called radiation. Although some forms of radiation can be harmful to life, some are not. Luckily, our atmosphere blocks most of the harmful radiation from reaching us.

Radiation comes in two general forms, electromagnetic and particulate.

Particulate radiation includes particles emitted from radioactive elements. In meteorology, we focus on electromagnetic radiation.

In the early 20th century, Einstein proposed the smallest unit of energy in radiation was a massless particle, now known as a photon.

Groups of photons moving through space constitute electromagnetic waves. They transmit energy through a vacuum and are invisible, although they can be detected using special instruments or our senses.

We characterize electromagnetic waves by their wavelength and frequency.

Wavelength is the distance between wave crests, and frequency is the number of wave crests passing a point in space per second. Therefore, the full range of possible wavelengths of light forms the electromagnetic spectrum.

Some wavelengths are very long, and others are short. Shortwave radiation includes gamma rays, x-rays, ultraviolet rays, visible light, and some infrared. Long wave radiation includes far-infrared, microwaves, and radio waves.

The visible light spectrum is what we can see with our eyes, which includes all the colors of the rainbow: red, orange, yellow, green, blue, indigo, violet, and everything in between!

We can't see any other wavelength in the spectrum without special instruments. However, it would be pretty cool to be like Superman and have X-ray vision and see different wavelengths.

Understanding how electromagnetic radiation interacts with our atmosphere and environment allows us to understand natural occurrences better and create technological advancements that help us in our everyday lives! Let me know in the comments what instruments that you know of enable us to see more of the electromagnetic spectrum!
