The shadow is cast on the opposite side of the object that the light source(s) is coming from. By the way im not too good with this kind of stuff.
when a shadow is formed there should be an opaque object the picture can be formed on the screen.
shadow
The object interrupts the journey of the light
When object is closer to source of light ,the shadow formed of the object is shorter and darker.
If the light is strong enough, a shadow is formed. But if that object is a cloud, a rainbow may be formed.

A shadow is formed when light is blocked by an object.
When a light (the sun) shines on you or any object, the object is in the way of the sunshine hitting the ground on the opposite side of the object, creating shade, or a shadow.
Shadows are formed when light shines on an opaque (solid) or translucent (partially solid, like a net curtain) object. This object stops the light rays, so a shadow is produced in the shape of the object. For example, if you hold your hand in front of a light, then the light will only be seen in the places where your hand is not blocking it. You will then see a hand shaped shadow.

The direction from which light hits an object determines the direction of the shadow it makes

when you change the object that creates the shadow by blocking the light, its' shadow will change. or there is another light source shining from a different direction on the object will affect the shadow too.
If you are using a point light source, the shadow's size is the object's size divided by the distance from the light source to the object multiplied by the distance from the light source to the shadow.
