Light Waves

Author: Nathan Lampson

 

Light waves are a form of electromagnetic radiation that can be detected by the human eye.  Unlike sound waves, light waves do not require a medium of particles in order to propagate.  Light waves can travel through the vacuum of space where no other particles are present.

Light is emitted and absorbed as tiny packets called photons, however, light can behave as a wave.  Light waves exhibit properties of both a particle and a wave. The energy of a light photon is linked to the wavelength of a light wave.  Shorter wavelengths of light are photons with higher energy.
