Wave length

Definitions

  • Webster's Revised Unabridged Dictionary
    • Wave length (Physics) the space, reckoned in the direction of propagation, occupied by a complete wave or undulation, as of light, sound, etc.; the distance from a point or phase in a wave to the nearest point at which the same phase occurs.

O'er yonder waves appear?
Our ardent vows at length prevail,
My heart proclaims them near.

Her mournful ghost is seen,
Or dimly o'er her infant's grave,

At length th' undaunted Scythian yields,
Content to live the Roman slave,
And scarce forsakes his native fields.

The earth, uplifting brute and man;
And mind, at length, in symbols dark
Its meanings traced on stone and bark.

And the sailors had lost nearly all their strength,
By striving hard their lives to save,
From being drowned in the briny wave.

And in the waves did sport and play,
Until at length the sun sank low
And then he thought it time to go.
Now just as luck would have it then
A prowling sea gull left his den.
