Solved: The effective incoming solar radiation per unit
Chapter 20, Problem 82P(choose chapter or problem)
The effective incoming solar radiation per unit area on Earth is \(342\mathrm{\ W}/\mathrm{m}^2\). Of this radiation, \(6.7\mathrm{\ W}/\mathrm{m}^2\) is absorbed by \(\mathrm{CO}_{2}\) at 14,993 nm in the atmosphere. How many photons at this wavelength are absorbed per second in \(1\mathrm{\ m}^2\) by \(\mathrm{CO}_{2}\)? (1 W = 1 J/s)
