Close your eyes and imagine you are in a forest. Then imagine a beam of light that will reach the earth 8 minutes after you get out of the sun. We all know that when the light is reflected from the leaf and the recipients in our eyes act, our brain perceives the color of the leaf as “green”. But what was the nature of the light really?
In the 17th century, the British scientist Isaac Newton thought the light was a tiny particle of hot matter, but the same century Huygens thought that the light was a wave that oscillated in every direction. But neither scientist could explain the exact nature of the light.
In the nineteenth century, the Danish scientist Orsted showed a sudden acceleration of the needle of the compass next to him during the opening and closing of a battery-powered conference. This experiment showed that the change from the electric field to the field formed a magnetic field, and that in this case, electric and magnetism were interrelated. Faraday, a well-known scientist, discovered that after 11 years the reversal of this state, the change in magnetic field, created the electric field.
The Scottish scientist Maxwell united these two situations under the single roof in the electromagnetism theorem and found that the change in electric field created the magnetic field, that the magnetic field generated again triggered the electric field and that this state entered the infinite recurrence by moving in space very quickly. It calculated that this extremely rapid movement travels in space at about 300,000,000 m / s, which is close to the speed of light we know
And from all these scientific proofs, the true definition of light; We can say that “the electric and magnetic fields move in space in such a way that they are not separated from each other”.
