And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think scientists know all the answers, but light continues to surprise them.

LIGHT definition: something that makes things visible or affords illumination. See examples of light used in a sentence.

Light in physics, its properties, colours, and behaviour, including reflection, refraction, and optics explained clearly.

In most situations, light behaves like a wave with properties like wavelength and frequency, and is subject to diffraction and interference. In some situations, light can be considered to behave like a …

light isn’t made of matter, so it doesn’t have mass. It is just a form of energy (also called electromagnetic energy) that travels at a constant speed from one place to another and reflects from the objects. …
