Wave Speed / Wavelength / Frequency Calculator implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Computation or source lookup only

Input and validation requirements

The string-wave formula divides by zero when linear density is zero, and negative frequency exposes an unresolved signed-versus-magnitude convention. The input-schema branch also requires explicit mode selection.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

  "inputs": {
    "f_Hz": 2.5,
    "lambda_m": 0.8
  },
  "expected_outputs": {
    "v_m_per_s": 2
  },
  "working": "v=fλ\nv=(2.5 s^-1)(0.8 m)\nv=2.0 m/s"
}
