is the idea of the photon different of what Einstein was alluding to in photoelectric effect?

Question

Photon a misnomer?Could that be the reason why no one is really able to explain what it is?

then according to the Uncertainty principle not two or more photon can be measured with the same energy package at any time=hence all photon are not the same ?and if they are particle waves they are different personalities hence differnt names?

Answer 1

A photon is a packet of light energy, a very specific (quantized) amount of energy, the exact amount depending on the frequency of the light.

How would a photon be a misnomer? In what way?

EDIT:
What are you talking about? Why would the Uncertainty principle prevent two photons being measured with the same energy.
Using the Plank constant, then energy of the photon is given as,
E = hv
where E is the energy, h is Plank's constant, and v is the frequency,
If we know the frequency of the light, we know the energy of the photons.

Would you care to back up any of these claims you are making.

Answer 2

A photon is a unit or packet of energy which is what Einstein believed. I don't understand what your question is except that you may be confused about the wave/particle properties of light--a phenomenon which is well understood today.

Answer 3

Nope, it's a "nomer." A perfectly fine name. Einstein was simply calling it as he saw it--this monochromatic wave apparently delivering its energy in discrete bundles.

This is the first explicit example of wave-particle duality to hit modern physics. Confusing, isn't it? Later on, DeBroglie tried to interpret material particles as waves, and this interpretation was confirmed with the first electron diffraction through crystals of nickel.

Answer 4

Yes, you are very astute.
