Science & Education

Optical Path Difference Calculator

Optical path difference Δ = n·d and phase δ = 2π·Δ/λ₀, classifying interference as constructive, destructive, or intermediate, with an optional round-trip mode for thin films.

Science & Education

Numerical Aperture Calculator

NA = n·sinα with the full acceptance cone and Abbe limit λ/(2·NA) — dry versus oil-immersion microscopy.

Science & Education

Rapidity Calculator

φ = artanh(β) with γ = cosh φ, γβ = sinh φ, the e^φ Doppler factor, and the tanh(2φ) additivity check — where boosts just add.

Science & Education

Relativistic Doppler Effect Calculator

Longitudinal Doppler: redshift 1+z = √((1+β)/(1−β)) for receding sources, blueshift for approaching ones, with observed frequency, wavelength, and band labels.

Science & Education

Relativistic Kinetic Energy Calculator

K = (γ−1)mc² with rest, total, kinetic, and classical ½mv² energies in MeV/GeV plus the K/K_classical ratio.

Science & Education

Relativistic Momentum Calculator

p = γmv with p·c in eV-scale units, the Lorentz factor, and the classical mv comparison for electron, proton, or custom mass.

Science & Education

Particle in a Box Energy Levels

E_n = n²h²/(8mL²) for preset or custom particles: zero-point energy, level ladder to n = 12, λ_dB = 2L/n standing-wave check, transition photon wavelengths.

Science & Education

Periodic Table Studio

Explore a clickable periodic table with live element details, color modes, and linked electron configuration data

Science & Education

Poynting Vector Calculator

Energy-flow density S = E × H = (1/μ₀) E × B with unit selectors, H = B/μ₀, both energy densities, and the plane-wave check where S = c·u.

Science & Education

Planck Blackbody Radiation Calculator

B_λ(T), Wien peak λ_max = b/T, M_λ = πB_λ at the peak and at any wavelength, and the Stefan-Boltzmann total σT⁴.

Science & Education

Malus's Law Polarization Calculator

I = I₀·cos²θ: transmitted intensity and percentage for any polarizer angle, with the 0°/45°/90° landmarks.

Science & Education

Quantum Harmonic Oscillator Energy Levels

E_n = (n + ½)ℏω from k + m, ω, or f: zero-point energy ½ℏω, equal spacing ħω, adjacent-transition photon wavelength, classical turning points, optional level ladder.
