When an electron and its anti particle position come close enough to each other, they Completely convert into radiation energy in the form of photons, this process Is called:
Correct answer: A. Annihilation
- A. Annihilation
- B. Pair production
- C. Compton scattering
- D. Photoelectric effect
Explanation
This is the correct answer. When an electron and its antiparticle, a positron, come into contact, they undergo a process called annihilation. In this process, the mass of both particles is completely converted into pure energy, which is emitted in the form of photons. This process is a fundamental interaction in particle physics and is essential for understanding the behavior of matter and antimatter.

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.
