Light is a form of electromagnetic radiation that is visible to the human eye. It is a type of energy that travels in waves and can be described by its wavelength and frequency. Visible light is just a small part of the electromagnetic spectrum, which includes radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays.
Here are some key aspects of light:
- Electromagnetic Radiation: Light is a form of electromagnetic radiation, meaning it is composed of oscillating electric and magnetic fields traveling through space.
- Wave-Particle Duality: Light exhibits properties of both waves and particles. As a wave, it has characteristics like wavelength and frequency. As a particle, it is composed of photons, which are discrete packets of energy.
- Visible Spectrum: The portion of the electromagnetic spectrum that humans can see is called the visible spectrum, which ranges from red (longer wavelengths) to violet (shorter wavelengths).
- Speed of Light: Light travels at a constant speed in a vacuum, approximately 299,792,458 meters per second (often denoted as c). This is the fastest speed at which energy or information can travel.
- Interaction with Matter: Light can be reflected, refracted (bent), absorbed, or transmitted when it interacts with matter. These interactions give rise to phenomena like color, shadows, and optical illusions.
