The document describes the phenomenon of rainbows. It explains that a rainbow is formed when sunlight enters water droplets, separating into the visible color spectrum of red, orange, yellow, green, blue, indigo, and violet. The document also notes that for a person to see a rainbow, the sun must be behind them with the rain droplets in front, forming an arc across the sky.

2. Rainbow
Rainbow is a spectacular phenomenon. A phenomenon
which a sequence is formed by the different colors. In
Indonesian, the colors called MEJIKUHIBINIU, it means
Merah, Jingga, Kuning, Hijau, Biru, Nila, and Ungu.
There are seven colors differently.
The rainbow is a large bow of a spectrum which occurs
because of the refraction of the sun light by the grain of
the water. In the sky, the rainbow appears to be a bow
light with the ends leading to the horizon at light rain.
The rainbow can also be seen in the vicinity of a strong
waterfall.
This phenomenon usually occurs when the air is very
hot at a drizzle. The rainbow could also be formed by

The process of colour parsing of the rainbow occurs
when the white sun light flowing into colour spectrum by
the rain. The colour spectrum consists of a red, orange,
the yellow, green, blue, indigo, and violet colour.
The light of the sun is polychromatic light (consisting of
many colours).The colour of white light of the sun
actually is a combination of various lights with different
long wave. The human’s eye can perceive at least
seven colours which conceived the sun light, that will be
looked at the rainbow: red, the orange, yellow, green,
blue, indigo, and purple.

4. Rainbow
The length of this light wave forms parallel line ribbon.
This ribbon is called a spectrum. In the spectrum, the
red line will always be on one side and blue and purple
on the other side and this is determined by a difference
of the wave length.
The rainbow is refraction of the sun light by water. When
the light of the sun goes through droplets of water, it
refracts through a glass prism. Thus, in droplets of
water, we have different colours extend from one side to
the other water droplets. Some of coloured light is then
reflected in the far side of the droplets of water, it is back
and out again from droplets of water.

5. Rainbow
Light is out from the water drops to different directions,
depends on the length of the wave. The difference in
this wavelength will bring out the colours of the rainbow
that composed by red at the top and purple at the
bottom of the rainbow.
The rainbow can only be seen when rain comes along
with the shining sun, but from the opposite side of the
observer. The position of the observer must be in
between the sun and droplets of water with the sun that
is behind the person .The sun, the eyes of the observer
and the centre of the rainbow should be in one straight
line.

6. RAINBOW
Have you
seen
rainbow???
*EXACTLY,
YES.
What’s
RAINBOW?
??

7. RAINBOW
RAINBO
W is a
sequence
of colors
differently
(7 colors)

8. Those are
the colors.
RAINBOW

9. RAINBOW
HOW IS RAINBOW FORMED??

10. RAINBOW
Spectacular
rays of color.
Sunlight
looks white,
but its really
made of
different
colors.
The white
light is made
of 7 colors.

11. RAINBOW
A rainbow is
seen when
the sun
shines after
the rain.

12. RAINBOW
The sun
makes
rainbow
when the
white light
passes
through rain
drops.
The raindrop
acts like tiny
prisms.

13. RAINBOW
When the
the white
light passes
rain drops, it
bends and
scatters into
the band of
colors.
This can be
reflected
back to you
as a
rainbow.
