Physics Calculators (Page 17)
Velocity, mechanics, energy, electricity and physics tools.
Rayleigh Criterion Calculator
Enter wavelength and aperture diameter to compute the diffraction-limited angular resolution θ=1.22λ/D. λ=550 nm, D=3 mm (eye) → θ≈46 arcsec; D=2.4 m (Hubble) → θ≈0.057 arcsec.
Mean Free Path Calculator
Enter molecular diameter, pressure and temperature to compute the mean free path of gas molecules.
Faraday's Law of Induction Calculator
Enter turns, magnetic field, coil area and angular velocity to compute the induced EMF in a rotating coil.
Mirror Equation Calculator
Enter object distance and radius of curvature (with optional object height) to compute image distance and magnification.
Relativistic Momentum Calculator
Enter rest mass and velocity to get relativistic momentum p=γmv, Lorentz factor γ, and energies. v=0.8c → γ=1.667, momentum 1.667× the Newtonian value.
Solenoid Magnetic Field Calculator
Enter turns, length and current to compute the solenoid interior field B=μ₀nI and total flux. N=1000, L=0.1 m, I=1 A → B≈0.0126 T.
Nuclear Binding Energy Calculator
Enter proton count, neutron count and nuclear mass to compute the mass defect Δm and binding energy E_B = Δm·c².
Otto Cycle Efficiency Calculator
Enter the compression ratio and specific-heat ratio to compute the ideal Otto cycle efficiency η = 1 − 1/r^(γ−1).
Schwarzschild Radius Calculator
Enter mass m to compute the Schwarzschild radius R_s=2GM/c², escape velocity and surface gravity. Sun 1.989e30 kg → R_s≈2.95 km; Earth ≈8.87 mm.
Bragg Diffraction Calculator
Compute diffraction angle from plane spacing and wavelength (Bragg's law).
Diesel Cycle Calculator
Compute ideal Diesel cycle efficiency from compression and cutoff ratios.
Cyclotron Frequency Calculator
Compute the cyclotron frequency f = qB/(2πm) of a charged particle.
