Answer:
Frequency is of light depends upon the body that emits it. While wavelength depends on the medium through which it travels in vacuum the product of wavelength and frequency is the same while in other mediums the light of higher wavelength travels faster besed on refractive index. So light velocity depends on both frequency and wavelength.

Fossil fuel use is integrated into the fabric of American society. Natural gas, petroleum and coal together accounted for more than 80 percent of energy use in the United States in 2012. Meanwhile, more than 5 gigawatts of solar power capacity was scheduled to come online in 2013 -- about as much capacity as was added for coal plants over a nearly 20-year span. The characteristics of solar power and fossil fuels drive the desire to adopt a particular energy source for a specific application, and they also limit the possible applications of a specific energy source.
