Varsha Manjesh 3 years, 11 months ago

To see an object, mainly, two things help us, Eyes and Light. Actually when a beam of light falls on an object from the source of light (mainly, sun) then this light gets reflected in all directions after striking that object. The reflected light then reaches our eyes and our brain interprets the object.
