Shorter wavelengths correspond to more energetic photons.

Question

Quizplus · Accepted Answer

This is a fundamental principle in physics known as the wave-particle duality. As electromagnetic radiation (including visible light) travels, it behaves like a wave, with different wavelengths corresponding to different colors. However, when it interacts with matter (such as when it is absorbed or emitted), it behaves like a particle called a photon. The energy of a photon is directly proportional to its frequency (or inversely proportional to its wavelength), so shorter wavelengths correspond to higher frequencies and more energetic photons.
