Answer:

The act of 'seeing' an object is the result of light from any luminous source e.g. the Sun, a glowing candle or a torch, radiating outwardly from the source until it strikes the object and is reflected to travel to the observer's eyes where if it retains sufficient intensity it will form an image on the retina. i hope this helps
