Energy is not continuous but comes in discrete packets called quanta. The energy [latex]E[/latex] of a single quantum of electromagnetic radiation (a photon) is directly proportional to its frequency [latex]\nu[/latex]. This relationship is defined by the Planck-Einstein relation, [latex]E = h\nu[/latex], where [latex]h[/latex] is the 플랑크 상수이 개념은 고전 물리학에 근본적인 도전을 제기했습니다.
