WebDec 13, 2014 · 6. Intensity has units of watts per area: [ I] = W m 2. where the area is the surface area of the emitting source (in this case, the sun). This tells you the total amount of radiation present (over all wavelengths). The extra factor of 1/nm in your plot gives the spectral irradiance : [ E] = W m 2 n m. This tells you the intensity at each ... WebHere is an experimental setup for the prismatic observation of the solar spectrum by Wollaston: Reproduced from Philosophical Transactions of the Royal Society of London, vol. 92 (1802), p. 380. In 1817 Fraunhofer took an even closer look at the Sun’s spectrum (IR, UV and visible) by expanding the spectrum onto a large wall.
