Who is the discoverer of the colors of sunlight
Good morning steemit Happy day bright with happiness
Sun light
The sun emits light in the form of electromagnetic waves, and man can see this light which is visible, and the rest of the light does not see the naked eye is invisible, and what distinguishes the sunlight that it consists of several colors from red to violet, known as rainbow colors, These colors and their energy vary in wavelength. The higher the wavelength of light, the less energy it has; the red color carries the longest wavelength, and the shorter it is to the violet, which carries the shortest wavelength
In the Middle Ages, some Muslim scholars (Ibn Sina) and al-Hassan ibn al-Haitham (the son of Ibn al-Haytham), and Ibn al-Haytham, were the first to study the light of the sun. He has many contributions to light such as: the state of the moon, rainbow, eclipses, eclipses, mirrors (the equilateral, spherical intersection), the first to know that light does not emanate from the eye; it falls on the eye and is transferred to the brain in the form of an image, Of his science is many and many scholars disagree Lord, and translated his book into Latin
No one came to study his theories and what he invented only seven centuries later by the English scientist (Isaac Newton) in 1666. He first discovered that the white light emitted several colors, and he used the publication that showed through this experiment that he It is possible to separate the colors from the white color, and this is the discovery that the rainbow is a natural physical state resulting from the refraction and analysis of sunlight through a drop of water
Types of solar radiation
In talking about solar radiation we point out that there are three types of them, namely
Thermal rays (invisible): These rays range in length from 0.75 to 40 microns. They are invisible, not visible to the naked eye and are known as infrared rays, and are estimated to be from the sun (46%).
Light rays (visual): These rays see the naked eye, and the length of the wavelengths between (40 0.74 microns) and the intensity of light rays in the afternoon during the summer, and the proportion of sunlight (45%). UV rays: These rays are also invisible, not visible to the naked eye. Its wavelength is between 0.1740 microns and is estimated to be about 9% of the sun's rays

ESteemIt is the best community around the globe so far. As of now the youth of today has been too busy wasting their time onto social networks that add to nothing except wasting precious hours of the day.
Whereas SteemIt is a total different story. You do what you like best BLOGGING and still get paid sitting at your homes.
I love steemit
This is beautiful 😍
I like sunrise
