<span>Which color in the visible spectrum has the highest frequency?
The color in the visible spectrum that has the highest frequency is the
violet.
</span>
Violet waves have the most energy of the visible spectrum.
Remember: <span> c=fλ</span>
Therefore: <span> f=<span>c/λ</span></span>
Here c is the speed of light in a vacuum.
So:
As wavelength decreases, frequency increases and, as <span>E=hf</span>, where h is constant (Planck's constant), so does the energy that the waves carry. Waves with a short wavelength have the most energy.
<span>Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter - roughly half that.
</span><span>Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.</span>
