In particular, the energy of a photon equals Planck's constant times the frequency of the radiation. Mathematically, this is given by the equation E = hf. Planck's constant is the fundamental constant of quantum theory that determines the scale of the small-scale world.lanck's constant = 6.63 * 10^-34 joule-second (J-s). The total energy in an electromagnetic wave is the sum of the energies of each photon in the wave. The energy of a photon is so small that we usually measure it in electronvolts (eV). One eV is the potential energy of each electron in a 1-volt battery.
A social revolution inevitably encounters an obstacle in the form of the political power of the ruling class. Hence, the first act of a social revolution is political revolution, the attainment of state power by the revolutionary class.
The Russian Revolution of 1905 was said to be a major factor to the February Revolutions of 1917. The events of Bloody Sunday triggered a line of protests. A council of workers called the St. Petersburg Soviet was created in all this chaos, and the beginning of a communist political protest had begun.ussia's first major battle of the war was a disaster: in the 1914 Battle of Tannenberg, over 30,000 Russian troops were killed or wounded and 90,000 captured, while Germany suffered just 12,000 casualties.
