In a subatomic world, things can be predicted with _ precision.
Correct answer: B. less than 1
- A. 1
- B. less than 1
- C. Absolutely no
- D. None of these
Explanation
In the subatomic world, predictions are made with less than-perfect precision due to the uncertainty principle in quantum mechanics. According to Heisenberg's uncertainty principle, it is impossible to simultaneously know both the exact position and momentum of a particle with arbitrary precision. This means that while predictions can be made about subatomic particles, they are inherently probabilistic and come with a degree of uncertainty, indicating a precision of less than 1.

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.
