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:

“So vulnerable.
She is already trampled, that one,
having traveled so far from the heart.
She weighs so little.
She is so light and vulnerable.
She is the dead bee called love.”
—Anne Sexton (1928–1974)

“Light, seeking light, doth light of light beguile;
So ere you find where light in darkness lies,
Your light grows dark by losing of your eyes.”
—William Shakespeare (1564–1616)

“The splendor falls on castle walls
And snowy summits old in story;
The long light shakes across the lakes,
And the wild cataract leaps in glory.
Blow, bugle, blow, set the wild echoes flying,
Blow, bugle; answer, echoes, dying, dying, dying.”
—Alfred Tennyson (1809–1892)
