wavelength derivations

  1. wavelength from frequency

    symbol

    description

    unit

    variable name

    \(c\)

    speed of light

    \(\frac{m}{s}\)

    \(\nu\)

    frequency

    \(Hz\)

    frequency {:}

    \(\lambda\)

    wavelength

    \(m\)

    wavelength {:}

    The pattern : for the first dimensions can represent {spectral}, {time}, {time,spectral}, or no dimensions at all.

    \[\lambda = \frac{c}{\nu}\]
  2. wavelength from wavenumber

    symbol

    description

    unit

    variable name

    \(\lambda\)

    wavelength

    \(m\)

    wavelength {:}

    \(\tilde{\nu}\)

    wavenumber

    \(\frac{1}{m}\)

    wavenumber {:}

    The pattern : for the first dimensions can represent {spectral}, {time}, {time,spectral}, or no dimensions at all.

    \[\lambda = \frac{1}{\tilde{\nu}}\]
