- Light radiates from a source in waves. Each wave has two parts; an electric part, and a magnetic part. That's why light is called Electromagnetic Radiation.

Oct 4, 2024 · Light sources are a type of particle accelerator that produce powerful beams of X-rays, ultra-violet, or infrared light. These beams are similar to how holding an envelope in front of a bright light can reveal something about what’s inside the envelope.
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz.

Photography is “writing with light.” So, let’s build our conversation about lighting on five fundamental characteristics of light: Direction, Intensity, Color, Contrast, and Hardness.
Light travels in a straight line.The speed of light is faster than sound. Light travels at a speed of 3 x 108 m/s.Reflection of light.The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization.
Following are the properties of light: Reflection of light: Every light follows the law of reflection which states that the angle of incidence is equal to the angle of reflection. Refraction of light: Refraction of light takes place when the light ray changes its velocity it passes from one medium to another.
Nov 14, 2024 · In its simplest form, quantum theory describes light as consisting of discrete packets of energy, called photons. However, neither a classical wave model nor a classical particle model correctly describes light; light has a dual nature that is revealed only in quantum mechanics.
Sep 30, 2022 · On one end of the electromagnetic spectrum are radio waves, which have wavelengths billions of times longer than those of visible light. On the other end of the spectrum are gamma rays, with wavelengths billions of times smaller than those of visible light.
Nearly every light source is polychromatic. White light is polychromatic. A graph of relative intensity vs. frequency is called a spectrum (plural: spectra). Although frequently associated with light, the term can be applied to any wave phenomena. A continuous spectrum is one in which every frequency is present within some range.

The total amount of light given off by a light source is called the luminous flux. It is measured in units called lumens. For example, a 100-watt incandescent lightbulb or a 26-watt compact fluorescent bulb emits about 1,600 lumens.
