Discover the power of quantum mechanics with the Planck’s Constant Calculator! This easy-to-use app allows physics students, quantum mechanics learners, and educators to calculate the energy of a photon (E = hν) or determine frequency from energy using Planck’s constant (h = 6.626 × 10⁻³⁴ J· s). Simply input frequency (Hz) or energy (J), select your calculation mode, and get instant results with real-time updates. The clean, intuitive interface ensures a seamless experience, while a brief note on Max Planck’s contribution to quantum theory adds educational value. Perfect for classroom use, homework, or exploring the fundamentals of quantum physics. Download now and simplify your quantum calculations!
