Final answer:
The wavelength of visible light with a frequency of 5.518 x 10^14 s^-1 is approximately 543.8 nm. The energy per photon is approximately 3.63 x 10^-19 J. The color of the light falls within the yellow-green portion of the spectrum.
Step-by-step explanation:
Visible light with a frequency of 5.518 x 1014 s-1 corresponds to a wavelength of approximately 5.438 x 10-7 meters, or 543.8 nm. The energy per photon can be calculated using the equation E = hf, where E is the energy, h is Planck's constant (6.626 x 10-34 J·s), and f is the frequency. Substituting the given values, the energy per photon is approximately 3.63 x 10-19 J. The color of the visible light with this frequency and wavelength falls within the yellow-green portion of the spectrum.
