then does it mean that coherent time is within the duration of a wave packet ?

then does it mean that coherent time period is within the duration of a wave packet ?

hi, as we know, lamp emits light not continuously but in 'burst', which we may call wave packet or photon. my question is, 1. Is it emitted one photon by one photon with random time delay ? 2. it is said that the duration time of the photon from white light is about 10^-9 sec(nanosecond), does...

hi, can anyone kindly explain to me what's 'coherent time' and 'duration of wave packet (photon)' in white light interference ?

hi, i want to know why scattering can occur when the light beam meet the particle, dust in atmosphere or molecules in water ..., but why not when they meet the glass surface and let the electrons in the glass surface be scattered? can anyone kindly help me, and tell me more about this ? thanks...

hi, i really confused about this two term. As i read from a book, ' in the Young's double slits experiment of light, if the time difference (that resulted from the path difference because of the two slits) is longer than the duration of each 'burst' (the photon),the received waves must come...

i don't know why the longer the wavelenght, the easier for it to be sattered ?
