Quantum
De Broglie Wavelength Calculator
Compute the de Broglie wavelength λ = h/(m·v) of a massive particle from its mass and velocity. Demonstrates wave-particle duality: every massive particle has an associated quantum wavelength.

Quantum
Hydrogen Atom Energy Levels Calculator
Computes the energy of any electron shell in a hydrogen atom using Bohr's model, given the principal quantum number n. Useful for understanding atomic spectra, photon emission energies, and introductory quantum chemistry.
