Question
What do you mean by mass energy equivalence? Give example.
✓
Answer
Mass-energy equivalence was propounded by Albert Einstein. It states that energy and mass are interconvertible. Example: An $\mathrm{e}^{-}$(electron) collides with an $\mathrm{e}^{+}$(positron) and the two annihilate giving two photons. The total mass of $\mathrm{e}^{-}$and $\mathrm{e}^{+}$is converted into energy.
