They are light travels in a straight line and light cannot pass through opaque objects./ some light cannot pass through translucent objects.
The property is that light travels in straight lines.(this is true only in normal gravitational conditions in very high gravitational fields this is wrong.) So when an object is placed in its path light cannot change its path thus forming an area where light doesn't fall.
A shadow is basically the places where no light, or less light, arrives.how
The property of light travelling in a straight line is called rectilinear propagation of light. When an opaque object obstruct the path of light this helps in formation of shadows
Light travels in a straight line
Because light travels in a straight line

That light cannot pass through some materials, and that this leads to the formation of shadows.
Shadows are formed when an opaque object comes in the path of light
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.
It is actually impossible to reflect a shadow, as a shadow is merely an absence of light. However, what IS reflected is the light surrounding the shadow. When this light is reflected, it forms a reflected image of the light's shape, complete with a lack of light, or shadow. In this way, it can look like a shadow is reflected.
Your shadow will fall in the direction opposite the source of light - with you between the light source and the shadow. The direction of your shadow relative to you will depend on what direction you are facing.If you are facing toward the light source, the shadow will be behind you.If you are facing away from the light source, it will be in front of you.If you have the light source to your right, the shadow will be to your left.If you have the light source to your left, the shadow will be to your right.If the light source is directly above you, the shadow will be directly under you.If you move past a light source, your shadow will move from behind you to beside you and then to in front of you.
That light cannot pass through some materials, and that this leads to the formation of shadows.
