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 Society of the Friends of the Constitution, better known as Feuillants Club, was a political grouping that emerged during the French Revolution. It consisted of monarchists and reactionaries who sat on the right of the Legislative Assembly of 1791. It came into existence on 16 July 1791 when the left-wing Jacobins split between moderates, who sought to preserve the position of the king and supported the proposed plan of the National Constituent Assembly for a constitutional monarchy; and rad
