Angular Wavenumber Solution

STEP 0: Pre-Calculation Summary
Formula Used
angular_wavenumber = (2*pi)/Wavelength
k = (2*pi)/λ
This formula uses 1 Constants, 1 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Variables Used
Wavelength - Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire. (Measured in Nanometer)
STEP 1: Convert Input(s) to Base Unit
Wavelength: 2 Nanometer --> 2E-09 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
k = (2*pi)/λ --> (2*pi)/2E-09
Evaluating ... ...
k = 3141592653.58979
STEP 3: Convert Result to Output's Unit
3141592653.58979 Meter --> No Conversion Required
FINAL ANSWER
3141592653.58979 Meter <-- Angular Wavenumber

What is Spectroscopy?

is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum; indeed, historically, spectroscopy originated as the study of the wavelength dependence of the absorption by gas phase matter of visible light dispersed by a prism.

How to Calculate Angular Wavenumber?

Angular Wavenumber calculator uses angular_wavenumber = (2*pi)/Wavelength to calculate the Angular Wavenumber, The Angular Wavenumber formula is defined as the number of radians per unit distance and is known as spatial frequency. Angular Wavenumber is denoted by k symbol.
