Light and Atoms

Light and Atoms

1. Light produced by the sun or any natural or artificial source of light is really electromagnetic waves.

   • Electromagnetic waves or EM waves are able to transport energy without transporting matter
   • Our main source of light is the sun, sunlight is composed of countless EM waves, each with different amount of energy
     • This composition of many EM waves is called "White Light" and its waves can be separated and seen in colors, by passing through a glass prism
       • This colors are the rainbow's colors and each color represents an amount of energy. Red haves the least while violet haves the most energy of the visible spectrum
       • When the white light reaches the prism it's separated into a colorful spectrum. Since this spectrum is continuous we can say that white light contains all the visible EM waves

2. The light we see is called white light and its made of many EM waves.

   • Energy can be produced by atoms, through light photons.
     • For an electron to change its orbit it must gain or release energy
       • But energy can also be absorbed, this is when electron gain energy.
         • But not all electrons can absorb the same amount of energy, which means that the absorption spectrum is different for each element
       • When electrons release energy they transmit light
     • The further the electron is to the nucleus the more energy it haves
   • This white light can be separated into a colorful spectrum. Each color representing an amount of energy
