Wave Number Solution

Follow our step by step solution on how to calculate Wave Number?

FIRST Step Consider the formula

k = \frac{2 \cdot π}{λ}

Next Step Substitute values of Variables

∴

k = \frac{2 \cdot π}{0.4m}

Next Step Substitute values of Constants

∴

k = \frac{2 \cdot 3.1416}{0.4m}

Next Step Prepare to Evaluate

∴

k = \frac{2 \cdot 3.1416}{0.4}

Next Step Evaluate

∴

k = 15.707963267949

LAST Step Rounding Answer

∴

k = 15.708

How to Evaluate Wave Number?

Wave Number evaluator uses Wave Number = (2*pi)/Wavelength to evaluate the Wave Number, Wave Number formula is defined as a measure of the number of oscillations or cycles per unit distance, which characterizes the spatial periodicity of a wave, providing a fundamental property of a wave in physics, particularly in the context of wave propagation and diffraction. Wave Number is denoted by k symbol.
