Wave per unit distance (typically per meter), can be associated with the wavelength by the relation The period formula_33 is the time for one complete cycle of an oscillation of a wave. The frequency formula_34 is the number of periods per unit time (per second) and is typically measured in hertz denoted as Hz. These are related by: In other words, the frequency and period of a wave are reciprocals. The angular frequency formula_28 represents the frequency in radians per second. It is related to the frequency or period by The wavelength formula_30 of a sinusoidal waveform traveling at constant speed
The Crests group continued as a trio of Carter, Ancrum, and Lewis and became a lounge act, disbanding in 1978. Carter went to sing with Charlie Thomas' Drifters for a year, then moved to Plainfield, New Jersey, to teach voice and set up his own recording studio. In 1973, Carter met his wife Leona, an accomplished classical pianist/composer. Leona Carter has been a part of The Crests since then. Carter reformed The Crests in 1980, auditioning over 200 singers at his studio, finally settling on lead Bill Damon (a Maestro sound-alike), Greg Sereck, Dennis Ray and New York drummer, Jon Ihle. The
