Planck's constant is analogous to:
Correct answer: C. Angular momentum
- A. Inertia
- B. Wave nature
- C. Angular momentum
- D. Linear momentum
Explanation
Correct option is C.Planck's constant is analogous to angular momentum.Furthermore, angular momentum has the same units as linear momentum multiplied with distance. So, we can find the dimensions of angular momentum. Hence, the dimensions of Planck's constant are equal with the dimensions of angular momentum.The unit for Planck's constant is kgm2s−1 The SI unit for angular momentum is kgm2s −1 Hence, they have the same SI units.

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.
