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.
The entire range of light, from radio waves to gamma rays, is known as the electromagnetic spectrum. The imaginary scene shown here highlights some of the natural and human-made sources of electromagnetic radiation on Earth and in space.
Light is a form of energy and like all energies, it is produced from a source. In Physics, these are called light sources. Types of Light Sources. There are countless sources of light, but they can all be categorized under either of the two following categories-Natural sources; Artificial sources; Natural Light Sources:

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 · Light is electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10 −11 metres to radio waves measured in metres.
