31. The course for the next four or five hundred feet had but little undulation . 32. The geometrical separation between it and the reference ellipsoid is called the geoidal undulation . 33. The land is mostly barren with slight undulation . 34. It achieves a kind of pulsation or undulation , rather than separating the notes. 35. I think the greens are a little too fast for the undulation on the greens, 36. Summer, in memory, seems almost like a plain of sunshine, without undulation . 37. There are a lot of greens above you and so many undulations to the fairways. 38. The geometrical separation between the geoid and the reference ellipsoid is called the geoidal undulation . 39. Damselfly nymphs swim by fish-like undulations , the gills functioning like a tail. 40. Calculating the undulation factor is mathematically challenging.
