EXPERIMENTAL INVESTIGATION ON THE REFLECTIVITY OF Al, Cu, Zn AND Ni AND ITS COMPARISON WITH THEORY

Abstract

The study is to generate accurate experimental results on reflectivity of metals and to compare them with the predictions made by theoretical models and also to predict values in longer wavelength range not covered by this experiment. The theories of the reflectivity of metals are first reviewed with respect to macroscopic and microscopic points of view. Apparatus was built for measuring normal spectral reflectivity by using a multiple reflection technique. Measurements of normal spectral reflectivity were made on the bulk surface of the pure metallic elements, copper, zinc, and nickel and high vacuum evaporated surface of pure aluminum. The measurements were made from 2 to 13 micrometers in air, at room temperature. Results are discussed.
