WebJan 3, 2024 · The formula to calculate the wavelength of a wave is: λ = v/f where: λ = wavelength; v = wave velocity; and f = frequency. You can rearrange this formula to calculate the frequency, given the wavelength of a wave. f = v/λ Verify the speed of the … WebQuantitatively, Wien’s law reads. λ max T = 2.898 × 10 −3 m · K. 6.1. where λ max is the position of the maximum in the radiation curve. In other words, λ max is the wavelength at which a blackbody radiates most strongly at a given temperature T. Note that in Equation 6.1, the temperature is in kelvins.
