What determines the frequency (color) of photons? - great science textbooks dvd library-torrent -download updated by
I have never been more in the science department, but I'm reading in front of my manual and I do not understand how this factor is colored as a whole?

So you now have an electron. Come forward and put it in an excited state. This is unfortunate, it is back to a state that is less energy. If he does, he has the energy is released. This can be done through the issuance of a discrete amount of energy as photons. The photon is a certain frequency (corresponding to the energy difference between states) and wavelenth. If the wavelength is about 390-780 nm, which can be seen by the human eye, and refers to a color. For example, blue corresponds to about 450 nm.
Wavelength (Lambda) = (speed of light c) / Frequency
The color is not to play. Exactly how our brain interprets different frequencies of light. In the visible range - 390-760 nm, we can identify different light. Cones (in the retina of the eye to work like this).
The energy change, which has freed when the photon. Higher energy means higher frequency and shorter wavelength.
