Anti matter theory was proposed by
Correct answer: C. Dirac
- A. Einstein
- B. Bohr
- C. Dirac
- D. Planck
Explanation
Paul Dirac, a British physicist, proposed the existence of antimatter in 1928. He was working on a relativistic equation for the electron, and his solution predicted the existence of a particle with the same mass as the electron but with an opposite charge. This particle was later discovered and named the positron.Dirac's theory revolutionized our understanding of matter and antimatter, and it laid the foundation for the development of particle physics.

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.
