A Shadow is the absence of light next to an area of light. The absence of light is caused by an object that is in the direct path of light so that light cannot reach the area that the shadow is in. Light cannot go around an object and is therfore blocked by objects creating an absence of light that is proportional to the object that is blocking the light.
You would either position the object creating the shadow perpendicular to the light source or move it closer to the light source.
