Plank׳s constant is analogus to:
Correct answer: C. Angular momentum
- A. Inertia
- B. Wave nature
- C. Angular momentum
- D. Linear momentum
Explanation
It is a fact that planck's constant is analogous to angular momentum as the two have the same dimensions.E=hνwhere dimensions of Energy, E are ML2T−2 and dimensions of frequency are inverse of Time Period, i.e. T−1Thus, ML2T−2=[h]T−1or, [h]=ML2T−1Now, angular momentum, L=Iωwhere units of omega are inverse of time (rad/sec, where radian is dimensionless).Units of I are ML2 (because I is of the form kMx2)Thus [L]=ML2T−1 ; T-1 because of rad/sec, considering that radian soesn't have a dimension, it would leave T-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.
