Light Is Energy seen as Visible light or felt as Heat etc released from the fusion of hydrogen and other elements in stars, visible light that you refer to is a small section of broader spectrum that as well as V light includes xrays, radio waves etc.

sound is the Vibrations that travel through the air or another medium and can be heard when they reach a person 's or animal 's ear.

A force is a push or pull upon an object resulting from the object 's interaction with another object.
