A simple example of a polarized transverse wave is vibrations traveling along a taut string (see image); for example, in a musical instrument like a guitar string.

Commission on Narcotic Drugs considers future of drug control. 14 March 2008 - The 51 st session of the annual Commission on Narcotic Drugs (CND) wrapped up today.
