Standing Waves (14 -39) (14 -41)

Standing Waves The Frequencies of Standing Waves (14 -43 a) 1. For a particular string, the standing waves with smaller wavelengths also have smaller oscillation periods. 2. For a given wavelength and string length, a less dense string vibrates more rapidly than a denser one. 3. For a given wavelength and string length, a string under more tension vibrates more rapidly than a string under less tension.
