Quantum Puzzle:Photoelectric effect

[cosmicraj]

Do any waves other than EMR show Particle Behavior in nature
(Like Sound Waves or Water Waves etc)?

In Photo Electric Effect We have considered that the light as packets of energy?
but it's equation of energy is \hbar \omega (h bar*omega)
and this\omega is the angular frequency of wave.
I could not understand that-If one is trying to explain the particle nature,then he has to explain that phenomenon with the particle properties.
But here Einstein is using the wave properties to explain the particle nature?
Could you please give me the reason Why?[/QUOTE]

Yes, other waves such as sound waves and water waves can exhibit particle behavior in nature. The Photoelectric Effect is a great example of this. In this effect, light particles (photons) interact with electrons on a metal surface and cause them to be ejected from the surface. This is explained using wave properties because the energy of the photons involves the angular frequency of the wave, which is related to its wavelength and frequency. By understanding the wavelength and frequency of the light, physicists can accurately predict the energy of the photon and, in turn, determine how much energy must be provided to the electron in order for it to be ejected.
