de Broglie Wavelength 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.

Effect

Computation or source lookup only

Input and validation requirements

The specification leaves hazardous edge behavior unresolved: zero momentum causes division by zero, v=c is outside the non-relativistic model although plain arithmetic produces a value, and signed velocity can produce a negative wavelength unless magnitude and direction conventions are separated.

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.
