What do radio waves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays have in?

They can all travel through a vacuum as electromagnetic waves. Infrared is lower frequency, but is similar to microwaves (like radar), or radio. Beyond visible light, the waves get shorter.

Gamma Rays can be down to the wavelength size of an atom...or the orbit of the electron that produce the wave...but such short energetic bursts are left to particle physics and you'll seldom see its observation outside outside the lab, except during at atomic test. The shorter the waves, the more influence it has atomically. Such as microwaves can heat water molecules in a microwave oven (the oven's secret), and infrared can heat too, but does it exterior to interior like a conventional oven.

You've just named off all the forms of radiation on the electromagnetic spectrum. All of those are massless photons traveling at light speed through a vacuum (186,000 miles per second). The only difference is their wavelength/frequency.

(Wavelength is the reciprocal of the frequency). The radio photons have very long wavelengths (low frequencies) and the gamma rays have very short wavelengths (high frequencies). Radio photons from space can't hurt your skin, but the very short wavelengths are very harmful to carbon-based lifeforms...so you want to avoid UV, X-rays, and gamma radiation photons.

Fortunately our atmosphere blocks all X-ray and gamma rays coming from the sun (by absorption collisions with the air), and most of the UV. But it's transparent to visible light, infrared (fancy name for heat), and radio photons. So that's the only difference, the wavelength of the photon.

(Read that - long wavelenth is low energy photons and short wavelength is very high ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
