Light

Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light has a wavelength in the range of about 380 nanometres to about 740 nm – between the invisible infrared, with longer wavelengths and the invisible ultraviolet, with shorter wavelengths.

Famous quotes containing the word light:

“Stern Daughter of the Voice of God!
O Duty! if that name thou love,
Who art a light to guide, a rod
To check the erring, and reprove;”
—William Wordsworth (1770–1850)

“Syncopations are no indication of light or trashy music, and to shy bricks at “hateful ragtime” no longer passes for musical culture.”
—Scott Joplin (1868–1917)

“For all this sea-hoard of deciduous things,
Strange woods half sodden, and new brighter stuff:
In the slow float of differing light and deep,
No! there is nothing! In the whole and all,
Nothing that’s quite your own.
Yet this is you.”
—Ezra Pound (1885–1972)
