Wave shoaling and the angular frequency is proportional to its local rate of change, Simplifying to one dimension and cross-differentiating it is now easily seen that the above definitions indicate simply that the rate of change of wavenumber is balanced by the convergence of the frequency along a ray; Assuming stationary conditions (formula_27), this implies that wave crests are conserved and the frequency must remain constant along a wave ray as formula_28. As waves enter shallower waters, the decrease in group velocity caused by the reduction in water depth leads to a reduction in wave length formula_29 because the nondispersive shallow water
The Crests & The Crests", producing a single for United Artists in 1962, two singles for Cameo Records in 1963-64, a single for APT Records in 1965, a single for Scepter Records in 1965, and three singles for the Parkway label in 1966. James Ancrum then took over the lead, recording "Guilty" in January 1962 and charting only to #123. The group went back to touring when their 1963 Selma side "Did I Remember?" flopped. A 1964 sequel to "16 Candles", "You Blew Out The Candles", also was not successful. In 1965, J.T. Carter and Mel Tillison signed with Decca Records and
