Intro:
(Yeah, yeah, yeah)
Lights collide, waves divide (uh-huh)
Patterns form, side by side (oh yeah)

Verse:
Start with a coherent wave source
Constant phase difference, take its course
Slits cut out, openings for light
Let those waves diffract with all their might

Chorus:
Path length difference, what a sight (sight, sight)
Half wave, whole wave, dark and light (light, light)
Path length difference, what a sight (sight, sight)
Half wave, whole wave, dark and light (light, light)

Verse:
Picture this, light passing through,
Two small slits, a breakthrough (oh yeah)
Diffraction starts, waves bend wide,
Meeting on the other side (let’s go)

Chorus:
Path length difference, what a sight (sight, sight)
Half wave, whole wave, dark and light (light, light)
Path length difference, what a sight (sight, sight)
Half wave, whole wave, dark and light (light, light)

Verse: 
Start at zero, central bright,
Half a wave, brings dark in sight
One full wave, the next bright show,
Patterns spread, they start to glow

Chorus:
Path length difference, what a sight (sight, sight)
Half wave, whole wave, dark and light (light, light)
Path length difference, what a sight (sight, sight)
Half wave, whole wave, dark and light (light, light)
