I read that a particle will meet its antiparticle and annihilate to generate a photon. Is it important for the pairs to be of the same type? What will happen when for example a neutron meets an antiproton or a proton meets a positron? Are there any rules to determine what happens when such particles meet?

a particle of unknown masss is observed to decay into 2 photons (mass:0) that have equal energies of 329 MeV. the opening angle between the 2 photon directions is 23 degrees. Find the mass of the unknown particle in MeV/c2. ( decaying particle moving. not necessarily to solve for energy, momentum and velocity)

Within the first second after the Big Bang the universe was filled with high-energy, gamma-ray photons. These photons created huge numbers of elementary particles and their antiparticles through pair production. What happened to these particles? They are still here. They combined to create the first atoms and molecules that compose the physical universe. The particles are still with us as atoms and molecules, but almost all of the antiparticles disappeared. These particle-antiparticle pairs annihilated to produce more photons. This pair...
Nuclear fusion reactions at the center of the sun produce gamma-ray photons with energies of order...
Nuclear fusion reactions at the center of the sun produce gamma-ray photons with energies of order 1 MeV (106 eV). By contrast, what we see emanating from the sun's surface are visible-light photons with wavelengths of order 500 nm. A simple model that explains this difference in wavelength is that a photon undergoes Compton scattering many times - in fact, about 1026 times, as suggested by models of the solar interior - as it travels from the center of the...

In the double-slit experiment, light particle is also called photon. Does the photons go through the slits in the double-slit experiment? What happens if you reduce the light to one photon and direct it at the duble-slit ? How are double-slits related to holograms?

By using photons of specific wavelengths, chemists can dissociate gaseous HI to produce H atoms with certain speeds. When HI dissociates, the H atoms move away rapidly, whereas the heavier I atoms move more slowly. Given that the bond energy of H-I is 300.4 kJ/mol, what is the longest wavelength (in nm) that can dissociate a molecule of HI?
