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:
“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)
“With love’s light wings did I o’erperch these walls,
For stony limits cannot hold love out,
And what love can do, that dares love attempt.”
—William Shakespeare (1564–1616)
“My paternal grandmother would not light a fire on the Sabbath and piled all Sunday’s washing-up in a bucket, to be dealt with on Monday morning, because the Sabbath was a day of rest—a practice that made my paternal grandfather, the village atheist, as mad as fire. Nevertheless, he willed five quid to the minister, just to be on the safe side.”
—Angela Carter (1940–1992)
