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) → Any

Summary

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
import numpy as np

✓

nu2lambda(np.array((1, speed_of_light)))

✗

array([3.e+08, 1.e+00])
