Lights dispel darkness is an adage that inspires people, yet !! - not this way !! on the roads of Metropolis, we often see people acting unmindful of harm that may befall on other road users and themselves as well !
In science, Light is electromagnetic radiation that the human eye can detect, and it can also be described as waves or as particles called photons. Visible light is only one part of the broader electromagnetic spectrum, which also includes infrared, ultraviolet, X-rays, radio waves, and more.
Darkness is not a thing on its own in physics; it is the absence or near-absence of visible light. That is why a room feels dark when no light is reaching your eyes, even though other forms of radiation may still be present.
We see objects when light from a source, or light reflected from an object, enters our eyes and is processed by the brain. If there is no visible light, the visual system has nothing to detect, so the scene appears dark.
Light is essential for vision, photosynthesis, and biological rhythms in living things. Darkness also matters biologically, because many organisms use it for rest, timing, and survival. A simple way to put it: light is incoming visible electromagnetic energy, and darkness is what we experience when that light is missing.
Provide knowledge to people to dispel the darkness of ignorance is the spiritual saying ! lighting of lamp (kuthuvilakku) is symbolic in every function, welcoming goodness and warding off evil.
Here the
motor cycle rider is carrying two big sized kuthu vilakku – which is disturbing
! “Light the lamp within and around you;
darkness cannot remain where light is kept burning”.
