一道光子数的题目（英文）
Find the number of photons incident on a detector in one second if the optic power is 1uw and the wavelength is 0.8 um.Compute and plot the photon energy in eV for a wavelength between 1260 and 1675 nm.

Answer 1

1μW = 10⁻⁶W = 10⁻⁶ J/sThe energy of each photon is E = hν = hc/λ = 6.6*10⁻³⁴*3*10⁸/(0.8*10⁻⁶) = 2.5*10⁻¹⁹ Jnumber of phot...
