Classification
Nouns denoting quantities and units of measure.
Examples
- The value of Planck's constant was first proposed by Max Planck in 1900 and has since been the subject of extensive experimentation and validation.
- Planck's constant is a fundamental physical constant that relates the energy of a photon to its frequency, and is denoted by the symbol h.
- In 2019, the International Committee for Weights and Measures redefined Planck's constant to be exactly 6.62607015 × 10^-34 J⋅s.
- The accurate determination of Planck's constant has far-reaching implications for many fields of science, including chemistry, physics, and materials science.
- Planck's constant is a critical component of the mathematical equations that describe the behavior of subatomic particles and the universe as a whole.
