What is Light :
Light is a thing, and it travels from one point to another.
Light is a form of energy, it can be transformed to heat energy through the process of Light Absortion
Not all light are absorbed, part of them are reflected.  That's how we see non-luminous object.
Reflection of Light :
Incident Angle = Reflected Angle
