Which of the following is not a substance of air or light?
The answer is. the light.
Light is not a substance unlike air. Light is both a particle and a wave, having the properties of particles and electromagnetic waves, but not all of the properties of both. Light is visible to the human eye, which is responsible for the sense of sight. Their wavelength ranges from 400 nanometers (nm), or 400 x 10 m, to 700 nanometers. Light also refers to electromagnetic radiation that travels from one transparent substance to another of different density, for example, from air to water. Furthermore, the term faster than light (FTL) refers to the transfer of information or matter. General relativity does not explicitly rule out faster-than-light, although this remains an open question. Therefore, light is not a substance like air.
Light is not matter, because it does not occupy space and has no mass. Air is a substance, it occupies space in space and has mass. Unlike air, light consists of photons, one of the most common and important forms of energy. In addition, light is both a particle and a wave, having the properties of particles and electromagnetic waves, but not all of the properties of both. Light is responsible for the sense of sight, with wavelengths ranging from 400 nanometers (nm) to 790 nanometers. Furthermore, faster-than-light (FTL) refers to the transfer of information or matter, although general relativity does not explicitly rule out faster-than-light.
Light is not matter while air is matter. Light is both a particle and a wave. It has the properties of particles and electromagnetic waves, but it does not have all the properties of both, because it is made up of photons. Light is responsible for the sense of sight, but anything that passes from one transparent substance to another of different density cannot be seen. Additionally, faster-than-light (FTL) refers to the transfer of information or matter, but general relativity does not explicitly rule out faster-than-light. Therefore, light is not matter, while air is considered matter because it occupies space and has mass.
