Waves
In homogeneous and isotropic solids, there are two kinds of waves, pressure waves and shear waves. The velocity of a shear wave, is controlled by the shear modulus,
where
- G is the shear modulus
- is the solid's density.

Famous quotes containing the word waves:
“With these I would be.
And with water: the waves coming forward, without cessation,
The waves, altered by sand-bars, beds of kelp, miscellaneous
driftwood,
Topped by cross-winds, tugged at by sinuous undercurrents
The tide rustling in, sliding between the ridges of stone,
The tongues of water, creeping in, quietly.”
—Theodore Roethke (1908–1963)
“The seashore is a sort of neutral ground, a most advantageous point from which to contemplate this world. It is even a trivial place. The waves forever rolling to the land are too far-traveled and untamable to be familiar. Creeping along the endless beach amid the sun-squall and the foam, it occurs to us that we, too, are the product of sea-slime.”
—Henry David Thoreau (1817–1862)
“There are no waves without wind.”
—Chinese proverb.
