- Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can travel through a vacuum. Light from the Sun reaches Earth through the vacuum of space.

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.
In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. [4][5] In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarization.
Light sources are necessary for vision. An object can be seen only if light travels from the object to an eye that can sense it. When the object is itself a light source, it is called luminous. Electric lights are luminous. The Sun is a luminous object because it is a source of light.

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.
