Light is propagated as ______ where its energy is ______ to its ______.

Light behaves as waves when we describe how it propagates. For electromagnetic waves, the energy carried by each photon is E = hν, and since ν = c/λ, this becomes E = hc/λ. So the energy is inversely proportional to wavelength: shorter wavelengths mean higher energy per photon, longer wavelengths mean lower energy. This aligns with the wave description and the photon-energy relationship. The other ideas mix in particle or ray language in ways that don’t tie energy to wavelength in the same way, and note that the speed of light in vacuum is constant and not inversely related to energy.
