a) What are the energies in electron volts (eV) of light at wavelengths 850, 1310, 1490, and 1550 nm? b) Consider a 1-ns pulse with a 100-nW amplitude at each of these wavelengths. How many photons are in such a pulse at each wavelength? a) What are the energies in electron volts (eV) of light at wavelengths 850, 1310, 1490, and 1550 nm? b) Consider a 1-ns pulse with a 100-nW amplitude at each of these wavelengths.
