WebRadiation spectra can be used to characterize radiation sources. Spectrometers measure relative spectral radiation over a specified wavelength range. Spectroradiometers are spectrometers calibrated to output spectral measurements in absolute units (e.g., energy flux density in W m -2 nm -1 or photon flux density in µmol m -2 s -1 nm -1 ... Webthe radiometer works, uninhibited by any established theory. The radiometer caused a sensation, most probably because it seemed to prove a direct pressure or repulsive force of light or heat. It thus had a direct bearing on the fundamental problem of the nature of light and radiation. It had long been thought that light
