Planck constant
This term refers to a specific, fixed value in physics, making it a proper noun phrase. It is used exclusively within scientific and academic registers, particularly in quantum mechanics and thermodynamics, to describe the quantization of energy.
Because it represents a single, universal physical constant, it is treated as an uncountable noun. It does not have a plural form in standard scientific discourse, as there is only one Planck constant for the universe.
Meanings
Examples
The energy of a photon is proportional to its frequency multiplied by the planck constant.
Do you know the exact numerical value of the planck constant?
The planck constant defines the scale at which quantum effects become significant.
I can never remember if the planck constant is written as h or h bar in this equation.
Without the planck constant, we would have no way to quantify the energy of individual quanta.
The professor explained how the planck constant relates to the photoelectric effect.
It is fascinating that a single number like the planck constant can govern the behavior of the entire subatomic world.
