21.2 Einstein and the Photoelectric Effect - Physics OpenStax

WebEinstein recognized that this could be explained by Plank's equation where one could define a "particle of light" or photon as having a fundamental energy of \[E_{photon} = h\nu\] in an electric field, it can kick an electron off the object and a current can flow. Einstein was able to use Plank's quantizations hypothesis to explain the ... WebAlright, so now we could figure out every possible photon this atom could absorb. If the electron's in the ground state, it could absorb a four eV photon, or a six eV photon, or a seven eV photon. If the electron's at the second energy level, also called the first excited state, the electron could absorb a two eV photon or a three eV photon. ctivitydependent refinement of cortical maps

5.1 The Behavior of Light - Astronomy OpenStax

WebAccording to the photon theory of light, photons: behave like a particle and a wave, simultaneously move at a constant velocity, c = 2.9979 x 10 8 m/s (i.e. "the speed of light"), in empty space have zero mass and rest energy carry energy and momentum, which are … Ionizing Versus Non-Ionizing Radiation . Electromagnetic radiation may be … WebABSTRACT. The idea of the photon has stirred the imaginations of physicists ever since 1905 when Einstein originally proposed the use of light quanta to explain the photoelectric … WebOct 7, 2024 · Figure 7.3.6: Absorption and Emission Spectra. Absorption of light by a hydrogen atom. (a) When a hydrogen atom absorbs a photon of light, an electron is excited to an orbit that has a higher energy and larger value of n. (b) Images of the emission and absorption spectra of hydrogen are shown here. ctive windows
