21. It has applied for a patent on a new wave form effective at much lower current. 22. A bow wave forms at the head of a swimmer when he moves through the water. 23. SlowGold can also display music as wave forms . 24. The two output wave forms are 90 degrees out of phase, which is what quadrature means. 25. Entrainment of intestinal slow waves forms frequency plateaus in a piece-wise manner along the intestine. 26. As an aircraft approaches the speed of sound, shock waves form on areas of greater curvature. 27. The computer analyzes the wave forms mathematically and reconstructs the sounds that have been distorted by crackles. 28. But in Gallery 5, LeWitt really spreads himself, extending his geometric grammar to _ a wave form ! 29. When the x-rays strike solid material they cause it to heat so rapidly that shock waves form . 30. Shock waves form when the speed of a fluid changes by more than the speed of sound.
