The process from rainbowRainbow is a large spectrum that happen
because of the refraction of sunlight by drops of water. When
sunlight through water droplets, it refracted. Some of the colored
light is then reflected from the far side of the water droplets,
back and out from water droplets.The light came back out of the
water droplets in different directions. Different wavelengths, will
bring the colors of the rainbow are arranged with red top and
purple on the bottom of the rainbow. Rainbow can only be seen when
the rain along with the sun shining, but from the opposite side of
the viewer.
How to see the rainbowThe position of the observer must be
between the sun and the water drops with the sun behind the person.
The sun, the eye of the observer and the center of the arc rainbow
shall be in a straight line. As a result, a rainbow formed from the
results of refraction and the position of the observer
