When no current is observed through the tube, the negative voltage has reached the value that is high enough to slow down and stop the most energetic photoelectrons of kinetic energy K max. This value of the retarding voltage is called the stopping potential or cut off potential V o. [11]
Photocurrent is the electric current through a photosensitive device, such as a photodiode, as the result of exposure to radiant power.The photocurrent may occur as a result of the photoelectric, photoemissive, or photovoltaic effect.
As the term suggests, an EM field consists of two vector fields, an electric field (,) and a magnetic field (,).Both are time-dependent vector fields that in vacuum depend on a third vector field (,) (the vector potential), as well as a scalar field (,)
Maximal kinetic energy and stopping potential in photoelectric effect on zinc: Width: 501.97363: Height: 336.99414
If Albert Einstein's photoelectric law is applied to a free molecule, the kinetic energy of an emitted photoelectron is given by =, where h is the Planck constant, ν is the frequency of the ionizing light, and I is an ionization energy for the formation of a singly charged ion in either the ground state or an excited state.
Prepare for potential side effects. Taking metformin may cause unpleasant side effects like diarrhea, nausea, upset stomach and, in rare cases, lactic acidosis.
A fatal virus has been discovered in shrews in Alabama, sparking concerns about potential contagion to humans. The Camp Hill virus was discovered by researchers at The University of Queensland.
In the clip, a devoted cat waits patiently outside his baby sister’s nursery door throughout the night. When morning arrives, the owner opens the door, and the eager feline makes a beeline for ...
