A shadow is formed when an opaque object blocks the path of light because light travels in straight lines.Light cannot bend around the object so it forms a shadow.

A shadow basically is a sort of image produced when light is blocked. A shadow generally takes up most of the space behind an opaque item with light right in front of it. The basic cross section of a shadow is generally a two-dimensional silhouette, or the overturned projection of the item obstructing the light.

For a non-point source of light, the shadow is distributed into the umbra and penumbra. The more extensive the light source, the more hazy the shadow will be. If there are numerous light sources there will be multiple light sources. For an individual or a subject touching the surface, like a human being standing of the earth, or basically a pole in the earth, these congregate at the tip of touch.

A shadow is formed when light travels in a straight line. A shadow does not seem to form on a cloudy day. It is a phenomenon that is commonly seen on a clear sunny day. If a person stands with his or her back towards the sun, he or she is sure to see his or her shadow, which appears to be following him. There are times when it appears as if the person is chasing or following his or her shadow.

The shadow of an object is formed when an opaque object or an opaque material is placed in the path of rays of light. The opaque object or material, unlike a transparent object or material, does not let the ray of light pass through it. The light rays go past the edges of the opaque object. This creates the outline of a shadow. The centre of the shadow receives no light at all. It is a dark portion known as the umbra. The lighter part is known as the penumbra. It receives some light from parts of the source of light.

Shadow is the darkness that one object causes when it prevents light from falling on a second object. As we know, light travels in straight lines. Thus, when an obstruction comes in its path, the rays striking on the obstruction cannot pass beyond and a shadow in the shape of the obstruction is formed on the surface on which the light subsequently falls. The process of formation of shadows helps us in formulating the photographic diagnosis by X-Ray.

Shadows can be quite helpful in our day to day lives. Shadow plays are enjoyed by all. Also, the shadow of a tree or a shade is a soothing place to rest under on a hot summer's day. Finally, we can tell the time on a sundial during the day by the position of a shadow cast by the sun.

Shadows are formed by light bouncing off an opaque object straight to our eyes.Let me give you an example, if in a room the light is on and there is a ball in the room. Will our eyes see the ball or not? Yes, we see the ball. The process of the eye seeing the ball is the light shines on the ball and the light on the ball reflects back to our eyes.

Shadows are formed by light hitting something but it cannot go through it. So then it becomes a shadow. REMEMBER LIGHT CANNOT BEND!!!

Shadows are created by an object blocking the path of the light source. Light travels in straight lines so light can not bind to go around the shape of the object it can only reflect off of the object blocking its path, same as you can not pass through a wall. The object that the light is being reflected from has to be opaque other wise light gets through it can also be translucent where only some light escapes from the object and passes through. An opaque object is something that you cannot see through such as your hand or a brick wall. When you put you hand in front of a light source such as a flash light you have a shadow. From what I have said none of the light can pass through your hand but the spaces around your hand, light can pass through so such as space between your fingers   will make light pass through creating the light around your hand around the shadow figure. I hope this helped you! LIGHT TRAVELS IN STRAIGHT LINES IT CANNOT BEND!!!!!!

The earth is constantly moving in its orbit around the sun so the angular relationship between the sun and the earth's equatorial plane is always changing. This is because the earth's axis remains oriented toward the same part of the sky all the way through its orbit. Since this relationship determines the length of a shadow it too must constantly change.
More specifically, the height of the sun changes from day to day. In the summer it is highest and in the in winter lowest. So as the  days go by from say, winter to summer, the sun gets a little higher each day, and thus your shadow shorter
