Options
It relates the frequency of radiation to the energy difference between quantum states
It determines the radius of the electron's orbit
It measures the size of an electron in the atom
It represents the speed of light in a medium

Solution
Planck's constant (h) is the proportionality constant that connects frequency to energy. It quantifies the relationship between electromagnetic radiation (characterized by frequency ν) and energy (characterized by ΔE). In the equation \[h\nu_{if} = E_{ni} - E_{nf}\], it establishes how the discrete energy differences between quantum states manifest as discrete photon frequencies, serving as a bridge between the quantum world and observable radiation.
