Formula for wavelength of light
WebIn the case of light, the frequency, symbolized by the Greek letter nu (ν), of any wave equals the speed of light, c, divided by the wavelength λ: thus ν = c/λ. A typical spectral line in the visible region of the spectrum has a wavelength of 5.8 × 10 −5 cm; this wavelength corresponds to a frequency (ν) of 5.17 × 10 14 Hz (hertz ...

If you know the frequency, or if you just calculated it, you can find the energy of the photon with Planck's formula: E = h × f; where h is the Planck's constant: h = 6.62607015E-34 m² ...
Webλ is the photon's wavelength; c is the speed of light in vacuum; h is the Planck constant; The photon energy at 1 Hz is equal to 6.62607015 × 10 −34 J ... This equation only holds if the wavelength is measured in micrometers. The photon energy at 1 μm wavelength, ... WebTo understand blackbody radiation and Figure 6.2.1 we need to rewrite Planck's law in terms of wavelength E = hν = hc λ I = nhν = nhc λ. The blue shift in the wavelength is because as E goes up, λ goes down. The increase in intensity is because as the temperature rises, n goes up. Example 6.2.1
WebWavelength is usually denoted by the Greek letter lambda (λ); it is equal to the speed ( v) of a wave train in a medium divided by its frequency ( f ): λ = v / f.
