उत्तर
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.
