Estimate (computing) how many photons a bulb with 100 W emitted per second in the visible range of light. Notes 1For simplicity, consider that: λ = 500 Nm
Etotal = x·h·f = x·h·c/λ Etotal corresponds to 100 W/s x is the number of particles at 500 Nm x = Etotal · λ / (h·c) x = 100J·500·10-9 m / (6.026·10-34 Js · 3.0·108m/s) x = 2.5·1020, i.e. about 1/1000 mol
Lösung:
