refraction
the object blocking the light or the light source are moved or changed. A shadow is created when an object is placed in the path of light. If the object remains unchanged then the movement of the light that is casting the shadow will alter the shape.
light did not had shadow and will not have shadow.
The shadow is caused by the light of the sun.

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.

Light travels in straight lines. When the light hits the object it is stopped but the light at the edges continues to travel in a straight line so there is a shadow.The shadow is not black because another property of light. It can be reflected . When it hits an object some light is reflected. If the object is not perfectly smooth the light is scattered when it reflects.Light is reflected more from light colored objects than darker objects. So in a well lit area where there are plenty of surfaces the shadow will be less dark.A further property of light is that it will slightly bend around the corners of sharp objects. So if you look carefully you will see that the edges of a shadow are sometimes blurred. Usually this property is observed in the physics lab.Blurred edges of a shadow are more likely to occur from multiple light sources making a superimposed shadow.
What causes a shadow, to begin with. Yep, a shadow is the blocking of light falling onto a surface. If you don't have light shining on a surface to begin with, say, at night, you cannot have a shadow.
light did not had shadow and will not have shadow.
get your airbag looked at it might need servicing
The direction from which light hits an object determines the direction of the shadow it makes
