The capstone audit joins one coherent semiconductor source chain. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

The LED source binds the emitted frequency to the gap

Band gap 6 joules with h equal to 2 joules per hertz gives frequency 3 hertz.

f=Egh=62=3 Hzf={E_g\over h}={6\over 2}=3\ \mathrm{Hz}
LED emission sourceThe emission check cites the same band-gap source.E_g=6 Jh=2 J/Hzf=3 Hzrecombinations=5E_total=30 J

Five recombinations carry thirty joules in the toy ledger

Five recombinations each use 6 joules, for total energy 30 joules.

56=30 J5\cdot 6=30\ \mathrm{J}
LED total energyThe total energy is a finite count ledger.E_g=6 Jh=2 J/Hzf=3 Hzrecombinations=5E_total=30 J

The capstone audit follows one source chain

The final accepted bit is 1 because gap, absorption, pairs, doping, junction, diode, and LED sources all match.
