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:
“There are no waves without wind.”
—Chinese proverb.
“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)
“And the waves sing because they are moving.
And the waves sing above a cemetery of waters.”
—Philip Larkin (1922–1986)
