# Observations Reshape Basic Plasma Wave Physics

April 06, 2017

[Paul M. Bellan](https://aph.caltech.edu/people/2927/profile), Professor of Applied Physics , and colleagues have discovered a new way to determine the wavelength of energy flowing through plasma in space—a method that was recently applied during a NASA mission that yielded the first solid evidence of how energy sloshes back and forth in a magnetic wave that moves through the plasma surrounding the earth.
