scipy.constants.nu2lambda#
- scipy.constants.nu2lambda(nu)[source]#
Convert optical frequency to wavelength.
- Parameters:
- nuarray_like
Optical frequency to be converted.
- Returns:
- lambdafloat 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([ 2.99792458e+08, 1.00000000e+00])
