Why do a shadow form behind the a tree?
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.
Why a shadow forms behind a tree?
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.
Why does a shadow form behind an opaque object?

What do you need to see a shadow?
To see a shadow, you need a source of light, an object to cast the shadow, and a surface for the shadow to be projected onto. When the light is blocked by the object, a shadow is created on the surface opposite the light source.
Why are you able to see the tree?
We are able to see the tree because light is reflected into your eyes. We see reflected light.
What does a black shadow mean?
if you see your shadow it means you blocked a light ray
Is shadow always black?
If Shadow is a horse, then no. Shadow may be white or brown. Else, if you are referring to a shadow produced by blocking out light with an object, then yes. When we do not see light, our view is in black. All other colours that we see are produced from light. Since shadows are created by excluding light from an object, we should only see black.
Why is your shadow sometimes in front of you and sometimes behind you?
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.
Why do you see shadows?
We see shadows when an object is blocking light. The shadow isformed because light can get around it, so you just see the outline.
What do you see of the phase of the moon first quarter?
You see the shadow of Earth cast upon the moon. The Sun's light creates the shadow and illuminates the quarter moon you see.
Is a shadow translucent?
The shadow is not a solid 'black' colour. It can be the same colour as the object and the shadow allows you to see through it more than an opaque objects shadow. An opaque object would block the light but a translucent object would give a shadow that you could quite easily see through
How do you see a tree because of light?
Light from the sun, or other light source, reflects from the tree into your eye. Structures in your eye focus the light onto your retina, which sends nerve signals to your brain. Your brain processes those signals and you "see" the tree.
