Physics Calculators (Page 26)
Velocity, mechanics, energy, electricity and physics tools.
Hydrogen Energy Levels Calculator
Enter initial and final quantum numbers to compute hydrogen energy levels, transition energy and photon wavelength via the Bohr model.
Quantum Harmonic Oscillator Calculator
Enter the angular frequency and quantum number to compute the energy levels, zero-point energy, and level spacing of a quantum harmonic oscillator. ω=1e14, n=0 → E=5.27e-21 J.
Particle in a Box Calculator
Enter mass, box length and quantum number to compute the energy levels of a 1D particle in a box E_n = n²·h²/(8·m·L²).
Bragg's Law Calculator
Solve Bragg's law 2d·sinθ = nλ and report if the condition is met.
Relativistic Doppler Calculator
Enter source frequency, speed and observation angle to compute observed frequency f'=f·√(1−β²)/(1−β·cosθ). Approaching θ=0, β=0.6 → f'=2f (blue); receding 180° → f'=0.5f (red).
Young's Double-Slit Calculator
Enter wavelength, slit separation d, screen distance L and order m to compute fringe spacing Δy=λL/d, bright-fringe position y_m=mλL/d and path difference. λ=550 nm, d=0.1 mm, L=2 m → Δy=11 mm.
Bernoulli Equation Calculator
Apply Bernoulli's equation along a streamline to find pressure/temperature/height relations.
Faraday's Law Calculator
Enter number of turns, magnetic flux change and time to compute the induced EMF ε = −N·ΔΦ/Δt.
Kepler's Third Law Calculator
Compute orbital period T = 2π√(a³/(GM)) from semi-major axis.
Curie's Law Calculator
Compute paramagnetic susceptibility χ = C/T (Curie's law).
Rocket Equation Calculator
Enter exhaust velocity, initial and final mass to get the velocity change and mass ratio. v_e=4500, m₀=100, m₁=10 → Δv≈10,362 m/s.
Quantum Tunneling Calculator
Enter the particle mass, barrier height and width, and energy to compute the transmission (tunneling) coefficient. Electron V=1e-18 J, E=5e-19 J, L=1 Å → T≈0.48.
