Deck the physics lab with lenses, fa la la . . .
Light bends more when they are densest,
We can now observe reflection,
Not to mention its direction, fa la la la la la la la la.

Stroboscopes are swiftly turning, fa la la . . .
While our eager minds are learning,
Light diffraction we can now see,
See how fun our physics can be, fa la la la la la la la la.
