Light
A source of light can have many colors mixed and in different amounts (intensities). A rainbow, or prism, sends the different frequencies in different directions, making them individually visible at different angles. A graph of the intensity plotted against the frequency (showing the amount of each color) is the frequency spectrum of the light. When all the visible frequencies are present in equal amounts, the perceived color of the light is white, and the spectrum is a flat line. Therefore, flat-line spectrums in general are often referred to as white, whether they represent light or something else

Famous quotes containing the word light:
“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)
“Lady of light, I would admit a dream
To you, if you would take it in your hand.
Will you not let it in a gentle stream
Of living blood? How else may I remand
Your light if not as pulse upon your ear?”
—Allen Tate (1899–1979)
“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)
