Hace 2 días · Max Planck rewrote Einstein's mass–energy relationship as M = E 0 + pV 0 / c 2 in June 1907, where p is the pressure and V 0 the volume to express the relation between mass, its latent energy, and thermodynamic energy within the body.
Hace 3 días · Einstein took as starting assumptions his recently discovered formula for relativistic Doppler shift, the laws of conservation of energy and conservation of momentum, and the relationship between the frequency of light and its energy as implied by Maxwell's equations.
Hace 3 días · Albert Einstein is best known for his equation E = mc 2, which states that energy and mass (matter) are the same thing, just in different forms. He is also known for his discovery of the photoelectric effect, for which he won the Nobel Prize for Physics in 1921.
31 de may. de 2024 · Einstein's seminal paper on special relativity in electrodynamics incorporated their so-called Lorentz transformation to explain why propagating electromagnetic waves were consistent with the existing laws of physics.
Hace 3 días · The speed of light in vacuum, commonly denoted c, is a universal physical constant that is exactly equal to 299,792,458 metres per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour).
15 de may. de 2024 · Light, according to Einstein, is a wave that interacts with matter as a packet of energy or a quantum of energy. The photon was the quantum of radiation, and the equation was known as Einstein’s photoelectric equation.
31 de may. de 2024 · photon, minute energy packet of electromagnetic radiation. The concept originated (1905) in Albert Einstein’s explanation of the photoelectric effect, in which he proposed the existence of discrete energy packets during the transmission of light.
