How does the distance between a light source and an object affect its shadow?
the moon
What affects was the size of a shadow?
The size of a shadow depends on, the angle that the light source is hitting the object and the size of the object. In some cases, the amount of light can also affect the size of a shadow.
What is the height of the shadow when the distance from the light source to object is 24cm?
It depends what angle the light is at, for example the shadow would be longer if the light was looking atr the object from the side (45 degrees) than it would be if looking at it from the top of the object(180 degrees).
If the position of my shadow how can you tell where is the light source?
ye
How does the time of day affect the direction of shadows?
Shadows are always directly opposite the light source. And the sun moves across the sky, the shadow will also move to remain on the opposite side.
Is the length of your shadow the same as your height?
No. Only if the ground is level and the light source is very far away and at a 45 degree angle.
What is the relationship between the size of the shadow and the distance of the object from the light source?
The relationship between the size of a shadow of an object and the distance of light source from the object is indirectly proportional. A short distance will make the shadow big while making the distance long will reduce the size of the shadow.

How does the length of a shadow get longer?
The light source moves strait above the object
what causes shadow length?
The length of an object's shadow is determined by ... -- the length of the object, -- the angle between the object's length and the surface on which its shadow appears, -- the distance between the object and the surface on which its shadow appears, -- the angular size of the light source as seen from the object, -- the angle between the direction to the light source and the normal to the object.
Why does the length and position of my shadow change as I walk towards a lamppost and away from the lamppost?
Light leaves the lamp and travels in straight lines from its point source. As you move away from the source, the angle between you and the light changes and this the length and position of your shadow changes.
Why when the length and position of my shadow changes as i walk towards a light source and when i walk away from the lamp post?
If the direction from which the light comes changes, then the direction of the shadow changes as well. The shadow basically points away from the light source.
What causes the shape of a shadow to change?
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.
The closer the light source the shadow is what?
The closer the light source the larger is the shadow. You can understand this effect using the paraxial aproximation of light theory. If you draw lines from the light source to the edges of an object, there is an angle (call it alpha) between the these lines and the orthonormal vector to the object. The shorter the distance between the light and the object, the higher is alpha (because the height of the object is always the same): tan(alpha) = (height of the object)/(distance between light and object) Of course the relationship between the height of the shadow and the angle is the same: tan(alpha) = (height of the shadow)/(distance to the wall in which the shadow is proyected) So, the higher the angle alpha (and closer the distance between light and object), the heigher is the shadow.
How tall is a bird bath that casts a 9 foot shadow?
That is an impossible question it could be any size the length of the shadow is dictated by the angle if the light source.
If a woman is standind and she is 64in tall with a 20in shadow and there is a lamppost that is 112in what is the length of the lampost's shadow?
If the lamppost is not the light source then lampost's shadow is 112/(64/20) ie 35 inches.
Does the size of the shadow of an object depend upon the size of the object?
because its telling you the sun is going nearer so it goes bigger because the sun is very big and the shadow changes because of the height and length of the sun on where it is this is my answer yea and um the flyers rock!
