According to physics, light is electromagnetic radiation to which the eyes react.
As a noun, light is defined as a source of illumination, radiance from a particular source, and also means daybreak. As a verb, light ignites, switches on, brightens, and illuminates. There are also expressions we use everyday that pertain to light, such as “going towards the light,” “coming to light,” “shedding light,” “bringing to light,” etc. While there are physical and technical definitions of light, light is also an abstract idea that has always fascinated and inspired humanity for eons. Light is a symbol for hope, goodness, curiosity, and the inexplicable. We chase after light, this intangible thing we strive to define, whether that be allegorical or literal.
