We heard many myths about this beautiful phenomenon that different cultures tried to explain, but what is the scientific explanation for it and how it occurs?
What is it :
The truth’s an optical phenomenon, resulting from the refraction ( seeming bending of light By the change in direction of a wave passing from one medium to another ), reflection (return of light, sound, or heat after being bounced off a surface ), and decomposition of sunlight through a drop of rainwater.
the rainbow appears after the fall of the rain or during the fall of the rain and the sun shines
and It is not located in a specific place or point in the sky due to that scientists describe it as
an optical illusion.
How it occurs:
Sunlight is white light and is made up of all the wavelengths of the visible spectrum.
when sunlight strikes raindrops (The water acts like a prism bending certain wavelengths of light ) in front of the viewer at a specified angle, the falling sunlight is refracted diagonally upon entering the raindrops and then is reflected into the inner surface of the droplet and is also refracted upon leaving the droplet, In incident light, the overall effect is reflected by a wide range of angles.
The colors are ordered by their wavelength, from longest to shortest: red, orange, yellow, green, blue, and violet.
This beautiful phenomenon can be caused by many forms of airborne water and it also
includes fog, spray, and air dew so spraying from a garden hose is a great place to look for
rainbows.
