Measurement: LengthUnit: m

Note: Value should be greater than 0.

Formulas to find Double Path

Integer part of Wave Length

Integer part of wave length is the coarser part of the larger wavelength measurement while the finer part is determined more accurately from the smaller wavelength measurement.

Symbol: M

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Integer part of Wave Length

Wavelength

Wavelength can be defined as the distance between two successive crests or troughs of a wave.

Symbol: λ

Measurement: LengthUnit: m

Note: Value should be greater than 0.

Formulas to find Wavelength

Fraction of Wavelength

Fraction of wavelength is the value we get when wavelength is multiplied to the phase difference.

Symbol: δλ

Measurement: LengthUnit: m

Note: Value should be greater than 0.

Go Integer Part of Wavelength for given Double Path

M = \frac{2D - δλ}{λ}

Go Wavelength given Double Path

λ = \frac{2D - δλ}{M}

Go Fraction Part of Wavelength

δλ = (\frac{Φ}{2 \cdot π}) \cdot λ

Go Fraction Part of Wavelength given Double Path Measurement

δλ = (2D - (M \cdot λ))

How to Evaluate Double Path Measurement?

Double Path Measurement evaluator uses Double Path = Integer part of Wave Length*Wavelength+Fraction of Wavelength to evaluate the Double Path, The Double Path Measurement formula is defined as it establishes the relation between the phase difference and the integer part of wavelength. Double Path is denoted by 2D symbol.
