Red is my favorite color. I love wearing this color. Do you like the color red?
1_Wizard
I do like red! It is actually at the end of the visible spectrum of light.

The visible spectrum includes wavelengths from 390 and 700 nm. The primary colors are red, green, blue.

What exactly are wavelengths and how do they work?
1_Wizard
Wavelengths are what human eyes can percept. Values outside the wavelength are detectable by computers!

Wow! That is really cool. So, computers can detect values that the human eye can not see?
1_Wizard
Indeed! For example infrared radiation is invisible to humans but detectable by science instruments!

I've heard of infrared radiation but I'm not that familiar with it. Is that the type radiation associated with microwaves?
