Normal light wavelength
WebWhen a beam of light crosses the boundary between a vacuum and another medium, or between two different media, the wavelength of the light changes, but the frequency … Web1 Answer. The reflectance of a typical mirror depends on the metallic coating used, but usually it is usually aluminum or silver in more expensive mirrors. Special optical coatings can be used to reflect or scatter EM waves at specific wavelengths. Here is a photo of a mirror reflecting IR (700nm - 1mm wavelength):
