Web13. okt 2024 · A perfect mirror can be defined as having a reflection R=1 and a phase change upon reflection of 180 degrees. The Fresnel formula for reflection at an interface of air with material at perpendicular incidence is R = 1 − n 1 + n. R is the amplitude reflection, the intensity reflection (energy) is R 2. WebThe 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):
