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:
“the whole sea become an entanglement of watery bodies
lost to the world bearing what they cannot hold. Broken,
beaten, desolate, reaching from the dead to be taken up
they cry out, failing, failing! their cries rising
in waves still as the skillful yachts pass over.”
—William Carlos Williams (1883–1963)
“What is Americanism? Every one has a different answer. Some people say it is never to submit to the dictation of a King. Others say Americanism is the pride of liberty and the defence of an insult to the flag with their gore. When some half-developed person tramples on that flag, we should be ready to pour out the blood of the nation, they say. But do we not sit in silence when that flag waves over living conditions which should be an insult to all patriotism?”
—Anna Howard Shaw (1847–1919)
“O beautiful for spacious skies,
For amber waves of grain,
For purple mountain majesties
Above the fruited plain!”
—Katharine Lee Bates (1859–1929)
