Fonction nu2lambda - module scipy.constants

Signature de la fonction nu2lambda

def nu2lambda(nu) 

Description

nu2lambda.__doc__

    Convert optical frequency to wavelength.

    Parameters
    ----------
    nu : array_like
        Optical frequency to be converted.

    Returns
    -------
    lambda : float or array of floats
        Equivalent wavelength(s).

    Notes
    -----
    Computes ``lambda = c / nu`` where c = 299792458.0, i.e., the
    (vacuum) speed of light in meters/second.

    Examples
    --------
    >>> from scipy.constants import nu2lambda, speed_of_light
    >>> nu2lambda(np.array((1, speed_of_light)))
    array([  2.99792458e+08,   1.00000000e+00])
