4. \( 800 \mathrm{Wm}^{-2} \) of radiant energy is incident upon a surface. 300 \( \mathrm{Wm}^{-2} \) is absorbed and \( 100 \mathrm{Wm}^{-2} \) is reflected. Calculate how much of that incident radiation is transmitted assuming the surface is not completely opaque. Sketch the diagram, list the knows on the diagram and state all assumptions in your solution.
