WebOct 3, 2024 · The peak wavelength formula is used to find the wavelength of a waveform that has the highest amplitude. This formula can be used for any waveform, but it is most commonly used for sinusoidal waveforms. … WebWien's Displacement Law. For a blackbody radiator, the temperature can be found from the wavelength at which the radiation curve peaks. Discussion. If the temperature is = C = K, then the wavelength at which the radiation curve peaks is: λ peak = x10^ m = nm = microns. This wavelength corresponds to quantum energy. hν = x 10^ eV.
