The size of a shadow has everything to do with placement of the light source, the object, and the background on which the shadow is cast. In general, if the light source is close to the object and the background is further away then the shadow is larger than the object. The opposite is true if the light source is further away. Another part of the equation has to do with angles. This is what we commonly observe happining to shadows at different times of the day; long shadows in the morning and evening and smaller shadows around the middle of the day.

What is the tree that has no shadow?
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.
How long is the shadow of a 5 feet 4 inch person if a 8 foot cast a 3 foot shadow?
8 feet and 5 feet 4 inches are in a ratio of 3 to 2 so therefore the smaller shadow is 2 feet in length
How do you use shadow method to estimate height or distance?
Measure height and shadow af a smaller object --- call these h1 and s1 measure the shadow of something larger like a tree. call this s2 its height is the unknown call it h2 use a proportion to solve the problem h1/s1 = h2/s2 substitute in the measured amounts, rearrange the equation (proportion) and find the answer.
What is the definition of shadow angle?
the angle at which a shadow is formed
When is our height shorter to our shadow?
When the sun is low down, the shadow is longer. If the sun is high up the shadow is shorter.
How can you make shadow bigger?
If you put your object further backwards your shadow will become bigger but if you put your object more forwards your shadow will become smaller!
How do you make a shadow bigger or smaller?
To make a shadow bigger, you can increase the size of the object casting the shadow, move the object closer to the light source, or decrease the distance between the object and the surface the shadow falls on. To make a shadow smaller, you can decrease the size of the object, move the object farther from the light source, or increase the distance between the object and the surface.
Do shadows get smaller or bigger?
Shadows get smaller as the light source moves closer to the object casting the shadow, and they get larger as the light source moves farther away. The size of a shadow is influenced by the distance between the object and the light source.
Is your shadow bigger or smaller when you are nearer to the light source?
Your shadow is smaller when you are closer to the light source because the angle at which the light hits you creates a shorter shadow. As you move away from the light source, the angle of the light changes, resulting in a longer and larger shadow.
What is smaller than you at midday and bigger than you late in the afternoon?
A shadow. It is smaller at midday when the sun is directly overhead, and longer in the late afternoon as the sun starts to set.
How can you make a shadow bigger?
If you put your object further backwards your shadow will become bigger but if you put your object more forwards your shadow will become smaller!
When is a smaller shadow formed?
at noon the shadow is point sized {smaller} and in morning and evening the shadow is the longest.
When an object is moved closer to the light source will the shadow become bigger or smaller?
There are many things that could happen when an object is moved nearer to a light or further away. It could change temperatures.
Is your shadow bigger or smaller when your closer to the sun?
Your shadow is smaller when you are closer to the sun. This is because the light source (the sun) is more direct, leading to less spread of light and hence a shorter shadow. Conversely, when the sun is lower in the sky, your shadow appears longer due to the light being spread out more.
What has a bigger shadow moon or earth?
The Earth's shadow is larger than the Moon's shadow because the Earth is much larger in size and has a greater surface area for casting shadows. The Moon's shadow is smaller in comparison, especially during a solar eclipse when the Moon passes between the Earth and the Sun.
Why do birds not cast their shadows while flyinghigh in the sky?
The shadow is there, but it is 'diluted' until practical invisibleness; spreading over a very big area and proportionally becoming lighter. Projection is a keyword here: The shadow is projected unto the nearest surface. If it is very close, the shadow is very dark. But there is only that much 'darkness' in a shadow. If the object is moved farther from the surface (e.g. the bird flying higher) the shadow becomes bigger, but less dense. The shadow is diluted until invisibleness, the smaller the rising bird, the faster. Try throwing an object up in the air in sunshine and see the effect. This explanation is true, but get a physics teacher explain it more scientifically correct.
When is a shadow smaller than the object casting it?
A shadow can be smaller than the object casting it when the light source is close to the object. This causes the shadow to be more compressed and appear smaller in relation to the object.
