Colors of Light
Visible light is the part of the electromagnetic spectrum that our eyes can
see. Light from the sun or a light bulb may look white, but it is actually a
combination of many colors. We can see the different colors of the
spectrum by splitting the light with a prism.
The spectrum is also visible when you see a rainbow in the sky.
The colors blend continuously into one another. At one end of the
spectrum are the reds and oranges. These gradually shade into yellow,
green, blue, indigo and violet. The colors have different wavelengths,
frequencies, and energies. Violet has the shortest wavelength in the visible
spectrum. That means it has the highest frequency and energy. Red has
the longest wavelength, and lowest frequency and energy.
Light in the Air
Light travels through space in a straight line as long as nothing disturbs it.
As light moves through the atmosphere, it continues to go straight until it
bumps into a bit of dust or a gas molecule. Then what happens to the
light depends on its wave length and the size of the thing it hits.
Dust particles and water droplets are much larger than the wavelength of
visible light. When light hits these large particles, it gets reflected, or
bounced off, in different directions. The different colors of light are all
reflected by the particle in the same way. The reflected light appears white
because it still contains all of the same colors.
Gas molecules are smaller than the wavelength of visible light. If light
bumps into them, it acts differently. When light hits a gas molecule, some
of it may get absorbed. After awhile, the molecule radiates (releases, or
gives off) the light in a different direction. The color that is radiated is the
same color that was absorbed. The different colors of light are affected
differently. All of the colors can be absorbed. But the higher frequencies
(blues) are absorbed more often than the lower frequencies (reds). This
process is called Rayleigh scattering. (It is named after Lord John Rayleigh,
an English physicist, who first described it in the 1870's.)
Why is the Sky Blue?
The blue color of the sky is due to Rayleigh
scattering.
As light moves
through the atmosphere, most of the longer wavelengths pass straight
through. Little of the red, orange and yellow light is affected by the air.
However, much of the shorter wavelength light is absorbed by the gas
molecules. The absorbed blue light is then radiated in different directions.
It gets scattered all around the sky. Whichever direction you look, some of
this scattered blue light reaches you. Since you see the blue light from
everywhere overhead, the sky looks blue.
As you look closer to the horizon, the sky appears much paler in color. To
reach you, the scattered blue light must pass through more air. Some of it
gets scattered away again in other directions. Less blue light reaches your
eyes. The color of the sky near the horizon appears paler or white.

makes to the Earth at Gandhi nagar junction at kanjurmarg in Mumbai. (File photo)
NEW DELHI: The second of the five supermoons of 2014 would be visible on
Friday, an organization working for popularizing astronomy said here Tuesday.
Space Foundation said the first supermoon of 2014 appeared Jan 1 - making
January the single calendar month with two supermoons until January 2018.
Friday's supermoon would be visible around 3.30 p.m.
The remaining three supermoons will be visible July 12, Aug 10 and Sep 9. The
one in August would be closest to Earth.
"A supermoon is when the moon makes its closest approach to Earth in its orbit
than usual. It appears as much as 14 percent bigger and 30 percent brighter," said
Space Foundation president C.B. Devgun.
According to the organization, the term supermoon came from astrologer Richard
Nolle over 30 years ago in 1979. During the phenomenon, the Earth, moon and
sun are all in a line, with the moon in its nearest approach to earth.
Prior to 1979, supermoons were called perigee full moon or perigee new moon.
