I now fully understand. Thanks folks. Really appreciate your help.
When a photon is absorbed, its energy is transferred to the absorbing material. This energy can cause an electron to move to a higher energy state, or it can be converted into heat. The information carried by the photon, such as its wavelength and direction of travel, is no longer present in the absorbed photon.
No, the information is not lost forever. The energy of the absorbed photon can be re-emitted in the form of a new photon, carrying the same information. This process is known as photon emission or fluorescence.
Yes, the information can be retrieved through various techniques such as spectroscopy, which measures the energy and wavelength of emitted photons, or through imaging techniques that capture the direction and intensity of emitted photons.
Yes, the information carried by a photon can affect its absorption. The absorption of a photon depends on its energy, which is determined by its wavelength. Different materials have different absorption properties, so the information carried by a photon can determine whether it will be absorbed or not.
No, the information carried by a photon cannot be changed during absorption. The energy of the photon is what determines its information, and this energy is transferred to the absorbing material without alteration. However, the information can be changed or manipulated after absorption through processes such as fluorescence or emission.
