LIGHT & OPTICS

Light includes electromagnetic waves of all sizes of wavelengths, frequencies, and energies. Light particles, called photons, have properties of particles and waves, a combination that makes light very interesting. With the invention of lasers, we have gained precise control over light and revolutionized many areas of research and technology.
