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.
Confidence votes 16.5K. The Russian Revolution was actually three revolutions. The first was in 1905, but it did not accomplish much aside from the creation of the weak Russian Parliament called the Duva.The Czarist regime maintained real power. The second was the February Revolution of 1917. This resulted in the abdication of Czar Nicholas II and the overthrow of the Czarist government.he first was in 1905, but it did not accomplish much aside from the creation of the weak Russian Parliament called the Duva.
