Answer: The shortest wavelength of light is the ultraviolet ray, which is the highest in Energy.
Step-by-step explanation:
- In the electromagnetic spectrum, we find the visible spectrum (roughly between 400 - 700 nm wavelength) between the ultraviolet (with wavelengths lower than visible) and the infrared (with wavelengths higher than visible, used by fiber optics in telecommunications).
- As there is a relationship inversely proportional between wavelength and frequency (which is the inverse of the period), if the wavelength is shorter, the frequency is higher.
- If the frequency is higher, this means that the light can change more quickly, which is a consequence of having more energy.
- This is clearly showed in quantum theory by this expression for the energy of one photon: E = hν, where h is the Planck Constant, and ν is the frequency of the photon.
