If there is another object within the boundary of the spheres cast shadow, would that object cast a shadow also. or will the shadow be the same tone as the spheres shadow and therefore disappear.
ideally the second shadow would be darker and there for be visible
Think about it logically - the shadow is cast because no light can pass through a solid object. Therefore how do you reason that an object with another object between it and its lightsource would cast a shadow?ideally the second shadow would be darker and there for be visible
It won't.
Stand outside your house on a sunny day, on the shadowy side. Do you see your shadow? :)
