The spectral reflectance curve, also known as the reflectance spectrum, illustrates how the reflectance of a material’s surface varies with the wavelength of light. Reflectance describes how a material reflects radiant energy/electromagnetic power and is, in general, a function of wavelength, polarization, and angle of incidence. Here is an interesting graph of the standard reflectance spectra for aluminum, silver, gold, and copper metals from a paper on photovoltaics: https://www.researchgate.net/figure/Standard-reflectance-spectra-for-aluminium-silver-gold-and-copper-metal-169-Graph_fig11_293329436
