Three nearby photon frequencies show that only exact equality fires the line. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Only the exact frequency closes the photon equality
With the training constant fixed at 1 joule per hertz, frequency 4 hertz gives photon energy 4 joules. The fixed transition gap is 5 joules, so the matched bit is 0.
E=hf=1⋅4=4J=5J,matched=0
Only the exact frequency closes the photon equality
With the training constant fixed at 1 joule per hertz, frequency 5 hertz gives photon energy 5 joules. The fixed transition gap is 5 joules, so the matched bit is 1.
E=hf=1⋅5=5J=5J,matched=1
Only the exact frequency closes the photon equality
With the training constant fixed at 1 joule per hertz, frequency 6 hertz gives photon energy 6 joules. The fixed transition gap is 5 joules, so the matched bit is 0.
