what do think is photon a quanta?
it is true to me that it is a quanta but i wish to gather solid evidence. i was think to gather evidence from photoelectric effect please see if you can give me additional insight

The basic argument (Einstein) was that increasing intensity led only to more electrons if they could be emitted. However if the wavelength was too long to produce photoelectrons, increasing intensity didn't help.

I can confirm that a photon is indeed a quanta of light energy. This means that it is the smallest possible unit of light, and it behaves both as a particle and a wave. This concept was first proposed by Albert Einstein in his explanation of the photoelectric effect, where he showed that light energy is absorbed and emitted in discrete packets, or quanta, rather than continuously. This has been further supported by numerous experiments and observations in the field of quantum mechanics.

In terms of gathering solid evidence, the photoelectric effect is a great place to start. This phenomenon occurs when light of a certain frequency is shone on a metal surface, causing the emission of electrons. The energy of the emitted electrons is directly proportional to the frequency of the light, rather than its intensity, which supports the idea of photons being discrete packets of energy. This effect has been well-studied and confirmed through various experiments, providing strong evidence for the existence of photons as quanta of light.

In addition, other experiments such as the double-slit experiment and the observation of the Compton effect have also provided evidence for the particle-like behavior of photons. These experiments have shown that photons can behave like particles with a defined energy and momentum, while also exhibiting wave-like properties such as interference and diffraction.

Overall, the concept of photons as quanta is well-supported by scientific evidence and has been crucial in our understanding of light and its interactions with matter. Further research and experiments continue to deepen our understanding of this fundamental particle and its role in the universe.
