Section 1. Energy from the Sun: Electromagnetic Radiation The energy, or heat, that streams from the Sun is electromagnetic (EM) radiation. In 1905, Einstein suggested that EM radiation can be described as a stream of tiny packets or tiny particles of light. These little \"packets\" of light are called photons and travel in a wave-like pattern at the speed of light (in a vacuum). Electromagnetic waves exist over a vast range of frequencies called the electromagnetic spectrum. Traditionally scientists have named regions of this spectrum.
