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 waves have now a redder glow—
The hours are breathing faint and low—
And when, amid no earthly moans,
Down, down that town shall settle hence,
Hell, rising from a thousand thrones,
Shall do it reverence.”
—Edgar Allan Poe (1809–1849)
“His bold head
‘Bove the contentious waves he kept, and oared
Himself with his good arms in lusty stroke
To the shore.”
—William Shakespeare (1564–1616)
“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)
