(But this is weird, this bring me an image of photon energy is contain at these numbers of cycles, besides, the no. of cycles may differ at different time interval)

Do you understand why it takes more energy to oscillate an electron rapidly then slowly? Then you understand why a high frequency electron has more energy then a low frequency one.

As in, KE = .5mV^2

OK, I'll tackle this one as well....

Forget about "photons" and E=mc^2 stuff. Let's just look at how we measure "energy" and use just simple, classical wave theory, shall we?

Now, if you look at simple wave theory, you'll see that the "energy" of the wave is related to the amplitude of the wave. Now, let's apply this to something simple such as a mass-spring system. the mass spring system will have more energy if the amplitude of oscillation is larger.

So far, so good.

Now, what if I have two mass-spring system, having the SAME amplitude, but oscillating with different frequencies? For the same of argument, let's have system 1 having frequency f1, while system 2 having frequency f2, where f2 = 2*f1.

Now, even though both are oscillating at the same amplitude, system 2 would have produced TWICE the energy of system 1 within the same time frame. In other words, system two has produced more POWER.

Now go back to one of the things I've asked you to consider, which is on how we measure energy. If you have a photodetector, you often have to specify if you're measuring power, or energy over a

So even without invoking the photon picture, one can easily explain such a thing, and this is where both the wave picture and the photon picture agrees with each other.

Zz.

If you increase the energy of the photon (better the electromagnetic fields) you get a contraction of the time (periodicity) of the fields itself, since the phase of a field must be lorentz invariant.

The variation of the energy of a fields (or particle) can be interpreted as a time dilatation/contraction effect.
