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.

∙ 15y agoShadow lengths change during the year because the Earth Rotates. When the Earth rotates it tilts meaning the sun would be on a different angle at different times of the year.

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.
Do all shadows look the same?
The length of your shadow depends on the angle on the Sun.If it is noon your shadow will be shorter than if It was at 3pm or 9am for at those times your shadow Will be longer.
How does the length of a shadow get longer?
The light source moves strait above the object
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 a shadow to change shapes?
the object blocking the light or the light source are moved or changed. A shadow is created when an object is placed in the path of light. If the object remains unchanged then the movement of the light that is casting the shadow will alter the shape.
If a nail is 50 millimeters in length what is its shadow length in millimeters?
Its shadow will be 50 millimeters in length, if you lay it down on a flat surface.
What kind of shadow causes phases of the moon?
it is not a shadow
How does the length of a shadow change during the yearwhy does this happen?
The length of the shadow (on a flat, horizontal floor) depends on the height of the Sun. If the Sun is higher in the sky, the shadow will become shorter.
Does the length of a sun stick control the distance a shadow moves?
yes the length of the sun stick does control the distance the shadow moves

What causes the length of the tree's shadow to change over the months?
The amount of sunshine, where the sun is, and if there is any sun at all. The angle of the light hitting the tree if the sun is high in the sky the Shadow is short for example if the sun is directly over a post then the post will cast no shadow. as the sun moves into a position that causes its light to shine on the side of the post a shadow will appear on the opposite side of the post where it blocks the sun. as the sun seems to assume a relatively lower position compared to the horizon it will make the shadow longer and longer.
Where was the light come from that causes the shadow of the umbra and penumbra?
The shadow is caused by the light of the sun.
How can you calculate height of a pyramid by measuring the length of its shadow?
By means of trigonometry if you know the angle of elevation or by comparing it with a nearby object if you know its height and shadow length.
What causes a strange shadow on the ground?
the sun
A tree is twice as high as the length of the shadow it casts The distance from the tip of tree to the tip of the shadow is 8 feet What is the length of the shadow that the tree casts?
We can not tell because we do not know how straight the tree is or if the ground is perpendicular or level.
