Electromagnetic Waves (To the tune of “The
Circle Game”, by Joni Mitchell)

Use an AC voltage source to emit
Waves traveling at c on any
Even through a vacuum they-
At mu-naught eps’lon-naught
to minus one-half.
For E and B fields James Maxwell found,
That their magnitudes go up
Traveling in a cosine wave
They retard by pi over two
Through a half-wave plate.
And go down and up and down
As they oscillate.
When passed through single slits waves will
From a straight line as they
They’ve theta-min at
lambda over a
And are observed with a photometer.
But through it all there was an argument
Of particle versus wave theory.
No answer though persistence
Was found until the 20th century.
Maxwell said EM waves could self sustain,
But photoelectric effect was
It was up to Einstein to explain
And thus to begin the quantum
