interference

opposites' attraction

leads to annihilation

two of a kind

are the ones that bind

gotta always remember

you don't need to wonder

waves of any type

on water or a rope tight

the good old light

quite different otherwise 

but for us now, alright

continuous patterns of low and high

when two waves meet

this is the way they greet -

if high meets high 

(tagging along, low complies)

they bind and grow

while if the high meets low

they annihilate, they are gone

altogether they are changed

they become one and same

water gets chunked

beams become a band

fine line, got to be coherent,

but this is interference.
