Who found an empirical relationship between the half-life of alpha decay and the energy of the emitted alpha particles in 1911?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Geiger and Nuttall.
- In 1911, Geiger and Nuttall discovered an empirical relationship between the half-life of alpha decay and the energy of the emitted alpha particles.
- This relationship, known as the Geiger-Nuttall law, states that for a given radioactive isotope, shorter half-lives are associated with higher alpha particle energies.
- This groundbreaking finding provided crucial insights into the nature of radioactive decay and helped establish the concept of nuclear physics.
