function
scipy.constants._constants:nu2lambda
source: build-install/usr/lib/python3.14/site-packages/scipy/constants/_constants.py:340
Signature
def nu2lambda(nu: npt.ArrayLike) → AnySummary
Convert optical frequency to wavelength.
Parameters
nu: array_likeOptical frequency to be converted.
Returns
lambda: float or array of floatsEquivalent 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 import numpy as np✓
nu2lambda(np.array((1, speed_of_light)))
✗array([3.e+08, 1.e+00])
