Guess what? Chemistry isn’t the only high school course built on a foundation of lies. In art class we’re taught that the primary colors are red, yellow, and blue. Not only is it wrong to say that there are three true primary colors, but if we were to pick three, we’d pick a better combination. Let there be light A band of wavelengths in the electromagnetic spectrum between 390nm and 700nm makes up the visible spectrum of light; we perceive different wavelengths within this spectrum as colors. White light is a combination of all wavelengths in the visible spectrum. Humans are trichromats, which means that we have three types of color receptors (cone cells). Our short-, mid-, and long…

Today I wanted to see what the average frequency of a song would sound like with no spectrum analysis or separation. I had a hunch that it would end up sounding like garbage, and I was totally right.
