- 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.

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.
We know light is radiated by a source of light, such as the Sun, light bulb, candle, torch etc. We also call these luminous sources . (Click to read the lesson sources of light )
The electromagnetic spectrum, with the visible portion highlighted. The bottom graph (Visible spectrum) is wavelength in units of nanometres (nm). Generally, electromagnetic radiation (EMR) is classified by wavelength into radio waves, microwaves, infrared, the visible spectrum that we perceive as light, ultraviolet, X-rays and gamma rays.
The light of such objects is incandescent. Other light sources emit light energy but no heat energy. They are known as luminescent, or cold light, sources. Neon and fluorescent lights are luminescent. Measuring Light. The total amount of light given off by a light source is called the luminous flux. It is measured in units called lumens.
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.
