Using a Cell Phone to Investigate the Skin Depth Effect in Salt Water
Rayner, John
Physics Teacher, v55 n2 p83-86 Feb 2017
This paper describes an experimental investigation of the skin depth effect for electromagnetic waves in salt water using a cell phone that is immersed to a critical depth where it no longer responds when called. We show that this critical depth is directly proportional to the theoretical skin depth for a range of salt concentrations.
