Mass and energy are related to each other by:
Correct answer: B. Einstein law
- A. Newton's law
- B. Einstein law
- C. Coulomb law
- D. All of these options are correct
Explanation
The correct relationship between mass and energy is described by Einstein's famous equation, E=mc², where E represents energy, m represents mass, and c represents the speed of light in a vacuum. This equation states that mass and energy are interchangeable; mass can be converted into energy and vice versa, with the speed of light acting as a conversion factor.

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.
