INVISIBLE SPECTRUM
When you look at a star, your eyes are capturing light that
travelled all the way from the star to your eye. Astronomers learn about
stars, nebulae, galaxies, and other faraway phenomena by collecting light
from them with specialized instruments. But they do not collect just the
kind of light your eyes can see. They also observe other kinds of light
that eyes cannot see. This invisible light includes radio waves,
microwaves, infrared light, ultraviolet light, X rays, and gamma rays. All
light, whether visible or invisible, is a kind of wave. These waves are
like the ripples that move along the surface of a lake after a pebble is
dropped. Light waves, however, are ripples in electric and magnetic
fields—which is why they are also called electromagnetic waves. There is no
fundamental difference between visible light and invisible light such as
radio waves and X rays. They are all electromagnetic waves that differ in
only one way: their wavelength. The term “wavelength” simply means the
distance from the peak of one wave to the peak of the next. The closer
together these peaks are, the shorter the wavelength. Radio waves,
microwaves, and infrared rays are electromagnetic waves with longer
wavelengths than visible light. Ultraviolet light, X rays, and gamma rays
all have shorter wavelengths than visible light. To observe these
wavelengths, astronomers use special instruments that can detect
wavelengths our eyes cannot.
Wavelength = Colo Wavelengths of light are measured in nanometres
(nm). One nanometre is a billionth of a meter. Visible light has
wavelengths ranging from about 400nanometers to 700 nanometres. Wavelengths
shorter than 400 nm, or longer than700 nm, are invisible to the human eye.
X rays can have wavelengths as short as a few thousandths of a nanometre,
while radio waves range from several meters to several thousand meters
long. The human eye sees different wavelengths as different colours. Red
light has the longest wavelength you can see (around 700 nm), and blue or
violet the shortest (about 400 nm). Wavelengths just longer than that of
red light are called infrared light. Wavelengths just shorter than violet
are called ultraviolet, or UV. These wavelengths can be thought of as
colours that your eyes cannot see. Visible or not? What’s the difference
between visible light and invisible light? It’s all in your head
—specifically, in your eyes. Whether a particular wavelength of light is
visible or invisible depends solely on which wavelengths your eyes can
detect. If your eyes were tuned to different wavelengths, new wavelengths
of light could become visible —and some colours you can see now might
become invisible. In fact, many animals see different wavelengths of light
than we do. Their eyes detect wavelengths that our eyes cannot. Bees and
butterflies, for example, can see ultraviolet light. Their eyes are tuned
to shorter wavelengths than ours. Certain fish and snakes can perceive
longer wavelengths than we can. They can detect infrared light (which we
feel as heat). To these animals, ultraviolet and infrared are like
additional colours of visible light.
Radios gather invisible radio waves and convert them to sound.
Cellular phones detect microwaves and convert them to sound. X-ray
cameras — like those used in airports — send X rays through objects, then
convert those X rays that pass through the object into visible light.
Infrared cameras detect heat leaking from houses to reveal where they need
more insulation. Televisions using antennas (not cable TV) detect radio
waves and convert them to visible light and sound, while satellite TV
dishes gather and decode microwaves. Hence invisibility or unheard of, do
not confirm the extinct but only our inability to see or hear.
So invisible spectrum is not a dreary science but had to take in
weighment to live with while using some and avoiding many in the welfare of
the society.
And the best universal language is sign and silence. Mounam sarvarta
sathagam or sadhanam. Meaning of silence is (A) Contentment is the greatest
happiness. (B) Keeping quiet makes everything work.
(C) Happiness is obtained only by giving up the shame in food, behaviour.
(D) Simple dealing with crooked people is not ethical. At the same time,
the Rowdram if not expressed ends in tragic life when the futurity is
sacrificed. Languages may be many but the mind understands everything even
when not spoken which are seen through the eyes and the ears mutually. KR
