Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps With the development of electric lights and power systems, electric lighting has effectively replaced firelight. What is light in physics 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. But what exactly is light
Is light a wave or a particle And why can’t humans see the whole spectrum of light Light is the first language of the cosmos Before humanity ever carved words into stone or etched equations onto chalkboards,… Something that makes things visible or affords illumination. See examples of light used in a sentence.
The observation and study of optical phenomena such as rainbows and the aurora borealis offer many clues about the nature of light as well as much enjoyment. Light travels from a source, like the sun or a light bulb, to our eyes, and to the surroundings That is the reason we can see objects during daytime with the sunlight, or with a light bulb in the night. 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 particle called a photon This particle has no mass, but carries a fixed amount of energy.
Light is a form of electromagnetic radiation, which means it has electric fields and magnetic fields vibrating back and forth very quickly as a wave Because of the strangeness of quantum mechanics, light is also made of little particles with no mass, called photons.
