The Physics Teacher

Volume 57 Issue 2, February 2019

 

This month's cover is an image from the 2018 AAPT High School Physics Photo Contest featuring the vivid, spectral-like array of colors of the Grand Prismatic Spring at Yellowstone National Park. What ideas does the rainbow ordering suggest to you? See “Visual Physics" for more detail from photographer Jean Zheng (University Transition Program, Vancouver, BC, Canada, Teacher: Ludmilla Shepelev) about this fascinating phenomenon.
