Quizplus · Accepted Answer

Wavelength ($\lambda$) of light is inversely proportional to its frequency ($f$) according to the equation $c = \lambda f$, where $c$ is the speed of light in a vacuum. Since energy ($E$) of a photon is directly proportional to its frequency ($E = hf$, where $h$ is Planck's constant), wavelength is also inversely proportional to energy.
