The mass-energy relation is the outcome of____________?
Correct answer: C. Special theory of relativity
- A. Quantum theory
- B. General theory of relativity
- C. Special theory of relativity
- D. None of these
Explanation
The relation E = mc² follows from special relativity, which treats mass and energy as equivalent forms of the same physical quantity. The likely mistake is choosing general relativity because it also concerns Einstein's theory, but general relativity primarily describes gravity and spacetime.

About Quantum Theory and Radiation
Quantum theory treats electromagnetic radiation as packets of energy called photons, with energy proportional to frequency through E equals hf. The topic covers Planck's hypothesis, photon momentum, the photoelectric effect, threshold frequency, work function and wave particle duality, distinguishing quantised energy exchange from classical continuous radiation.
