Animals that have brightly colored
wings, is known as a beautiful and graceful animal. Hence, many beliefs
consider the peacock as a symbol of beauty, fidelity, eternity and peace. But,
there are some things that are not less privileged of India's national bird. As
the following facts.
Habitat peacock in the forest and rain
forest that are found in the regions of India, Pakistan, Sri Lanka, Southeast
Asia and Central Africa. Peacock love to eat seeds, berries, leaves, flower
parts, insects and small creatures.
Peacocks live in groups and form a
family. They live in trees at night. And in the daytime, they prefer to walk on
the ground and perched on bare tree branches.

was only held by a male peacock, not a female. Because this beautiful wings
used by male peacock to attract the female. Meanwhile, the females do not have
a long tail feathers in order to hide and lay eggs safely in the bushes.

subjected to manhunt. As a result, the population has continued to decline, and
if left unchecked could lead to extinction. In addition to its coat, peacocks
are also hunted for meat. Meat peacock believed to be a cure for arthritis.
peacock feathers are very close
together works much like a thin layer of oil on the surface of the water or
thin layer of rock. When sunlight
which consist of several wavelength fall on a peacock’s feather, some of the
wavelengths will be subject to constructive interference, according to the
different thicknesses of the feathers. The constructive interference from
various colors (or various wavelengths) create bright light of different colors
on the feathers, as shown in the picture
The same
phenomenon can be seen on soap bubbles and oil that float on the water surface.
Hence, the colors on a peacock’s feathers, soap bubbles, and oil are caused by
optical effects; does not originate from the objects themselves.

To understand the facts in this life we need to understand well about physics matter, but unfortunately, many of us do not like physics subject specially for children nowadays.
