[Intro]
White light enters
(Slowing down)
Wavelength splinters
(Bending round)
[Verse 1]
How does a rainbow know
(Which way to go)
Raindrops act
(Reflect and refract)
[Chorus]
White light enters
(Slowing down)
Wavelength splinters
(Bending round)
[Bridge]
Exacting (refracting)
Shorts got the blues
Erecting (reflecting)
Sure’s got the hues
Cannot disparage
(Dispersion)
[Verse 2]
Into the prism schism
(Change in medium)
Refraction separation
(Into the spectrum)
[Chorus]

A SCIENCE NOTE
A prism or a rainbow separates colors through a process called dispersion, where light is refracted (bent) as it passes through a medium with varying refractive indices for different wavelengths.
In a prism:
- White light enters, slowing and bending due to the change in medium.
- Shorter wavelengths (blue/violet) bend more than longer wavelengths (red).
- This separation spreads the colors into a spectrum.
In a rainbow:
- Raindrops act like prisms, refracting and reflecting sunlight.
- Different wavelengths emerge at slightly different angles, producing the arc of colors visible in the sky.
