London Math. Soc. 9 22 The following particular cases..are here tabulated for convenience:—V ∝ λ, U = o, Reynold's disconnected pendulums. V ∝ λ1/ 2, U = 1/ 2V, Deep-water gravity waves. V ∝ λ0, U = V, Aërial waves, &c. V = λ−½, U = 3/ 2V, Capillary water waves. V ∝ λ−1, U = 2V, Flexural waves. 1912 H. Lamb in Proc. 5th Internat. Congr. Math. (1913) II. 284 This [formula] is illustrated in the case of gravity waves. 1930 W. N. Shaw Man. Metereol. III. i. 30 The genesis of gravity-waves in air is not generally understood. 1957 Jrnl. Marine Res. 16 107 At wind velocities between 16 and 20 knots it is common for capillary waves having the same velocity as the gravity waves to ride just at the beginning of the crest of the gravity waves. 1971 Nature: Physical Sci. 29 Mar. 99/2 The excitation of atmospheric gravity waves by a nuclear test in the atmosphere. < as lemmas |
