how is heat transferred ...?
I could not give myself satisfying explanation for this:
When a photon(s) hit my skin (from sun) why do i feel warmth? Simplier, why does sunlight warms my skin?
I know that photon warms atmosphere when it gets absorbed by atom/molecule. This absorbtion must increase kinetic energy of that elements. (thats how temperature is defined).
Is this how it happens on my skin? The photon increases vib/rot energy of my atoms?
To ask more explicitly: It is not the kinetic energy of photon that matters, but the frequency, right?
If some one has some clear explanation how photons warm my skin, i would be glad to get educated.
thanx
