Pair production minimal wavelength is the shortest wavelength of a photon that can spontaneously produce an electron-positron pair in a vacuum.
The minimal wavelength for pair production depends on the energy of the photon and the presence of a charged particle, such as an atomic nucleus, to absorb the excess energy.
Pair production is one of the ways in which matter is created in the universe. When high-energy photons interact with matter, they can create an electron-positron pair, which adds to the total number of particles in the universe.
Yes, pair production can occur in a vacuum as long as there is sufficient energy present to create an electron-positron pair.
Pair production minimal wavelength is an important concept in quantum physics and is used in various fields such as particle physics and astrophysics. It also has applications in medical imaging and radiation therapy.
