Photons
So I'm understanding the general concepts we have been discussing during lecture and the problems we have been practicing, but I'm kind of confused with what exactly a photon is. I know it's a particle that makes up all kinds of light, but if you had to define it in succinct terms without missing any key concepts we have discussed, how would you describe it?

Re: Photons
Photons are little packets of light that can be described in terms of particle and waves. Your textbook does a pretty good job at discussing wave-particle duality in greater detail.

Re: Photons
Photons, as I understand, are referred to has being "massless" even though they have energy.

Re: Photons
Photons are small particles of light that are said be massless and have both wavelike properties which is shown in the diffraction experiment and also contains particle properties which can seen in the photoelectric experiment.

Re: Photons
Hello everyone! Also, it is important to remember that different photons of different particles have different frequency. So, a beam of red light contains small photons, or packets of energy, all consisting of the same energy. Moreover, the intensity of the radiation indicates the number of photons present while the equation E=hv refers to the amount of energy of each individual photon.

Re: Photons
Hey,
One more small thing to also remember is that in general, energy is proportional to frequency and is inversely proportional to wavelength, remembering this makes solving problems where you're asked a problem with 2-3 frequencies or energy levels a lot easier, especially because you kind of know what to expect relative to your other answers
