comment the temperature of photon and its energy
Indeed, the maximum in the spectrum connects the radiation wavelength, $\lambda_{max}$ at the maximum, and temperature of the hot object as $\lambda_{max}T=2.9\times 10^{-3}$mK (Wien's Displacement Law).

comment What does the Copenhagen interpretation say about the position of a particle before measurement?
@Gugg I hope the explicit mention of the Copenhagen interpretation in the edited answer (see bf text) will suffice?

comment What does the Copenhagen interpretation say about the position of a particle before measurement?
@Gugg Thanks for the comment. That is a valid point, but the discussion is about the Copenhagen interpretation indeed. A detailed discussion to cover all vital points, would take a whole book. I am Sorry if I have misinterpreted the point you are trying to make. -:)

@Mia You need to tell us the given information in the question, and what you need to calculate.

comment How do you calculate power at the focal point of a mirror?
@BrandonEnright You have used the AM0 solar spectrum. The AM1 (at one atmosphere absortpion) solar spectrum is only 925 W/m$^2$.

comment Deriving equations of motion using integration
@SaurabhRaje No it doesn't get stuck. You need to know the force. If you know the force is for example $F=-kx$, then $a(x)=-(k/m)x$ and you integrate that. If you don't know what kind of force acting on the object, you will not know how it is going to move.

comment Deriving equations of motion using integration
@SaurabhRaje These are two independent cases. I discussed the example with the constant acceleration, $a(x)=a$, to show you the versatility of the general equation (1). You need to be able to distinguish one case from the other.

comment Do protons exchange photons with electrons?
@DanPiponi When two particles echange energy (photons) their energy and momentum do change. You need to take into account that the exchange of virtual photons lasts a very short time, for the electron or proton to climb or tunnel through the potential well. The proton does recoil, but this recoil is very small and pulls the electron with it anyway. This is how hydrogen atoms can move about without getting ionized by the slightest impact.

comment Do protons exchange photons with electrons?
@Dan The simple analysis I presented does not rediscover the wheel. It simply shows consistency of the two pictures. You can do the analysis for the Proton-positron case (repulsive "force") in a similar, but not identical way.
