Why the physicists are doing that? Figure 2 a Figure 2 b 3.
The physicists exchange the word photon as they talk, so it must be digestible information.
Abstract Despite Planck was recognized as the originator of quantum physics, he struggled for it throughout his life until his death.
In my own view, the resultant energy could not be greater or lesser than the sum of the two separate intensities.
I say this is true quantitivily.
All I can do is offer a qualitative description.
The intensity of light incident upon unit area, a, per unit time can be written as: 2 Where, r, is the distance from the source.
Since, the mathematical equation is the simplest form to express the relation between the physical quantities and shows the physical meaning, one can write the energy radiated from the monochromatic source as: 1 Where N is the number of emitted wavy rays from the source, b is the energy contained in each wavy ray section, ν, is the frequency of the wavy ray and T is the illumination time.
