The ultra-violet transmission-band of metallic silver, as affected by temperature

Abstract

The reflecting power of metals in general falls off towards the blue end of the spectrum. This may readily be verified in a qualitative manner by placing a candle between two reflecting surfaces and observing the train of images. These, in all cases that I have tried, become redder as we proceed along the train. Silver, however, differs from the other white metals, in that there is a fairly sharp minimum of reflexion in the near ultra-violet. This was first observed by Stokes.
