Light travels in straight lines and therefore some will hit the tree. Where this happens a shadow (absence of light) is created behind the tree.
Well, no trees have a shadow if it is dark, or if they are shaded by a bigger tree. But a family tree may have no shadow.
Let the height of the tree be x: x/10 = 5/4 x = 50/4 The tree is 12.5 feet
4.5 ft
Measure the tree with the meter stick.
We can only see something if light is reflected off it. Our eyes see shadows because there is less light reflected from the shadow than the surrounding area.
The tree blocks the sunlight, preventing it from reaching the area behind the tree, creating a shadow. Light travels in straight lines, and when an object obstructs its path, it cannot pass through. This causes the area behind the tree to receive less light, creating the shadow.

Light from the sun (or any other source) travels in particles, which strike objects and are often partially absorbed. A shadow forms behind a tree because when the particles hit the tree, they are absorbed and reflected, so that everything on the other side of the tree, where the light would have gone, receives no light. However, some light will bounce off of other objects and go behind the tree in the other particles' place. Since this other light will already have been partially absorbed, it will be more dim than direct light. Because of this, we are able to see in the shadow, but since the light there is not as strong, it is darker. This darker region behind the tree, is the shadow.

A source of light and an object that blocks the light are needed for a shadow to form. The area behind the object where the light is blocked creates the shadow.

because light passes through, and you cant have a shadow with light on now can you?
Well, no trees have a shadow if it is dark, or if they are shaded by a bigger tree. But a family tree may have no shadow.
A shadow forms when an object blocks the path of light. In the case of the sun shining, the object blocking the light is you, which casts a shadow behind you. The sun's rays are not able to pass through your body, creating the shadow on the ground.
When the sun is shining in your face, your shadow will be behind you.
