We have a sum of three waves, which can be expressed as

<math>\Psi _{Front Of Diamond} = C _1 A \sin ( \omega t + d _1 ) </math>

<math>\Psi _{Front Of Diamond} = \Psi _1 = C _1 A \sin ( \omega t + d _1 ) </math>

<math>\Psi _{Back Of Diamond} = C _2 A \sin ( \omega t + d _2 ) </math>

 

<math>\Psi _{Mirror} = A \sin ( \omega t) </math>

<math>\Psi _{Back Of Diamond} = \Psi _2 = C _2 A \sin ( \omega t + d _2 ) </math>

 

<math>\Psi _{Mirror} = \Psi _3 = A \sin ( \omega t) </math>

(For simplicity, we will say that the wave leaving the mirror has not been phase-shifted.)
