Since light always travels at the same speed, we can correlate a wavelength for each energy. Additionally, our eyes see a different color for each energy.https://photonreport.com/wp-content/uploads/2017/05/fluorescence-schematic.jpgFluorescence schematicFluorescence is a process whereby a higher-energy photon is absorbed and a lower-energy one emitted, along with some heat (in the form of vibrations) so that energy is conserved.2017-06-20T23:43:34+00:00monthlyhttps://photonreport.com/2017/05/21/all-about-phase/https://photonreport.com/wp-content/uploads/2017/05/spherical-wave.jpgSpherical WaveA small slit illuminated with light acts as a point source of light emitting spherical waves. As the light travels to a distant screen, some parts of the wave will have travelled farther and therefore acquired more phase.https://photonreport.com/wp-content/uploads/2017/05/phase.jpgphaseLight waves can add. If they are in-phase, peaks add to larger peaks (and troughs become deeper), which can be visualized by looking at the displacement of an electron. For out-of-phase light, the electron will not be displaced and there is pure darkness.2017-06-20T23:38:58+00:00monthlyhttps://photonreport.com/2017/06/12/coherence/https://photonreport.com/wp-content/uploads/2017/05/whitelight-coherence-feature.jpgWhitelight coherence featurehttps://photonreport.com/wp-content/uploads/2017/05/spatial-coherence.jpgspatial coherencehttps://photonreport.com/wp-content/uploads/2017/05/whitelight-coherence.jpgWhitelight coherencehttps://photonreport.com/wp-content/uploads/2017/05/temporal-coherence-1.jpgTemporal Coherence 12017-06-16T23:08:02+00:00monthlyhttps://photonreport.com/2017/05/07/hello-world/2017-05-10T02:09:38+00:00monthlyhttps://photonreport.com/contact/2017-05-07T02:12:19+00:00weekly0.6https://photonreport.comdaily1.02018-12-04T01:58:05+00:00
