The Physics Teacher

Volume 58 Issue 8

November 2020

This month's cover is "The Color of Money" by Peppino Sapia at the Università della Calabria in Rende, Italy. It features a 100 Euro note and highlights the sophistication of the anti-counterfeiting measures evident in modern paper currency. The sequences bounded by red and blue margins show how the appearance of the inset images change when the angle of incident light is changed. The illuminating light is the Nitecore CU6 440 Lumen UV LED flashlight (white light and 365 nm UV light) and the photos have been taken face-on using a Nikon D3200 digital camera equipped with a micro lens f=105 mm.

Since August 1, 2014, the submission process for articles for The Physics Teacher has required authors to submit their article and cover letter at this website:  Starting June 10, 2020, the submission process for articles for The Physics Teacher will change.   On or after June 10th, authors should submit their article and cover letter at this website:
