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. 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. The meaning of light is something that makes vision possible How to use light in a sentence
Light is a transverse, electromagnetic wave that can be seen by the typical human The wave nature of light was first illustrated through experiments on diffraction and interference. Light is a type of energy that enables us to see with our eyes 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
This particle has no mass, but carries a fixed amount of energy. But what exactly is light In spite of theoretical and experimental advances in the first half of the 19th century that established the wave properties of light, the nature of light was not yet revealed—the identity of the wave oscillations remained a mystery This situation dramatically changed in the 1860s when the scottish physicist james clerk maxwell, in a watershed. Light, that portion of the electromagnetic spectrum visible to the human eye. Heinrich hertz’s production in 1888 of what are now called radio waves, his verification that these waves travel at the same speed as visible light, and his measurements of their reflection, refraction, diffraction, and polarization properties were a convincing demonstration of the existence of maxwell’s waves
