sci.gravitational-wave-strain Calculator
Calculates gravitational wave strain h = ΔL/L and estimates the required interferometer arm length for detection from source parameters. LIGO detected the first gravitational wave (GW150914) with strain h ≈ 10⁻²¹ — a deformation of 10⁻¹⁸ m over 4 km arms, smaller than a proton.
Inputs
Chirp Mass Solar
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
Luminosity Distance Mpc
Separation between two points or total path length. Check that units are consistent throughout the calculation.
Frequency Hz
Cycles per second (Hz). Audible sound: 20 Hz – 20 kHz. Make sure units match what the formula expects.
Results
GW strain h
Fractional deformation: change in length / original length. Elastic strain is fully recoverable; plastic strain is permanent. Plotted vs. stress on a stress-strain curve.
chirp mass (kg)
The computed mass of the object or substance.
distance (Gpc)
The computed distance or separation.
h = 4/D × (GMc)^(5/3) × (πf)^(2/3) / c⁴
