Pair production is possible in _ Photon.
Correct answer: C. Gamma rays
- A. X-rays
- B. Beta rays
- C. Gamma rays
- D. All of these options are correct
Explanation
Pair production is a quantum phenomenon where a photon is converted into an electron-positron pair. This process requires the photon to have energy greater than 1.02 MeV, which is typical for high-energy gamma rays. While X-rays can theoretically induce pair production, they rarely have the necessary energy in most practical situations. Beta rays are not photons and cannot cause pair production. Therefore, gamma rays are the most likely candidate for this process.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
