Question

Quizplus · Accepted Answer

The energy of a photon is given by E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength. Solving for λ gives λ = hc/E. Substituting the given energy (210 kJ/mol converted to J/photon) into this equation gives the longest wavelength as approximately 5.7 × 10^-7 m.
