Light of Class 8
An old-age debate that has persisted among scientists is related to the question, "Is light a wave or a stream of particles?" Very noteworthy and distinguished physicists have taken up each side of the argument, providing a wealth of evidence for each side. The fact is that light exhibits behaviors that are characteristic of both waves and particles.
Light is a form of electromagnetic wave that causes the sensation of vision.
The wave nature of light was first illustrated through experiments on diffraction and interference.
Like all electromagnetic waves, light can travel through a vacuum.
The transverse nature of light can be demonstrated through polarization.
Light is sometimes also known as visible light to contrast it from "ultraviolet light" and "infrared light".
Other forms of electromagnetic radiation that are not visible to humans are sometimes also known informally as "light"
