Light travels very quickly in straight lines and in waves.
Good question, Ella. Light is a form of energy.
Wait....How do you create light?
You must be reading my mind, Joe! I was just about to explain. Light is created by atomic transition, accelerated charged particles or the object is luminous.
That means it creates its own light, for example it can be created by heat, chemical reactions, and many more things. Examples of luminous light are bioluminescence, fluorescence, chemiluminescence, phosporecence, etc.
