A light wave is a type of electromagnetic radiation that is visible to the human eye. It is a complex phenomenon that exhibits both wave-like and particle-like properties, a concept known as wave-particle duality. Light waves are transverse waves, meaning that their oscillations are perpendicular to the direction of their propagation. They travel in the form of oscillating electric and magnetic fields that are in phase with each other. The speed of light in a vacuum is a fundamental constant of nature, approximately 299,792 kilometers per second (km/s). Light waves are characterized by their wavelength, frequency, and energy, with visible light having wavelengths ranging from about 380 nanometers (violet) to 750 nanometers (red). Other types of light, such as gamma rays, X-rays, microwaves, and radio waves, are also considered forms of light but are not visible to the human eye.

In this sense, gamma rays, X-rays, microwaves and radio waves are also light. Like all types of light, visible light is emitted and absorbed in tiny "packets" called photons and exhibits properties of both waves and particles. This property is referred to as the wave�Cparticle duality.
