Shadow length refers to the distance from the base of an object to the tip of its shadow, which is cast by a light source, typically the sun. The length of a shadow varies depending on the angle of the light source, the height of the object, and the time of day. During midday, when the sun is highest, shadows are shorter, while they become longer in the morning and late afternoon. Shadow length can also be influenced by the object's shape and the surface on which the shadow falls.

How do you find shadow height?
To find the height of a shadow, you can use similar triangles. Measure the height of the object casting the shadow and the length of the shadow itself. Then, using a known reference height and its corresponding shadow length, set up a proportion: (height of object)/(length of shadow) = (height of reference)/(length of reference shadow). Solve for the unknown height.
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 three things do length and position of a shadow changing depend on?
The length and position of a shadow depend on the angle of the light source, the distance between the object and the surface the shadow falls on, and the height of the object casting the 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
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?
Since the tree is twice as high as the length of the shadow, we can set up the following equation: 2x = x + 8, where x is the length of the shadow. Solving the equation gives us x = 8 feet, so the length of the shadow that the tree casts is 8 feet.
What is the length of your shadow at midday?

What factors effect the length of a shadow?
The length of a shadow is primarily influenced by the angle of the light source, which is often the sun. When the sun is low in the sky, such as during sunrise or sunset, shadows are longer; conversely, when the sun is overhead, shadows are shorter. Additionally, the height of the object casting the shadow and the surface on which the shadow falls can also affect its length. Environmental factors like obstructions and the time of year further contribute to variations in shadow length.
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 shadow length?
The length of a shadow is primarily determined by the angle of the sun in relation to the object casting the shadow. Shadows are longer in the early morning and late afternoon when the sun is lower in the sky, and shorter at midday when the sun is directly overhead. The size and shape of the object casting the shadow also play a role in determining shadow length.
How would the length of the shadow at noon compare with the length of the shadow in the late afternoon?
At noon, when the sun is at its highest point in the sky, shadows are typically at their shortest because the sunlight is coming directly overhead. In contrast, during the late afternoon, the sun is lower on the horizon, causing shadows to lengthen significantly. Therefore, the length of the shadow at noon is much shorter than the length of the shadow in the late afternoon.
What would the length of shadow cast by a pole be if the incident rays of the sun were direct?
I am not sure what you mean by "direct" - light tends to travel in a straight line. The length of the shadow depends on the length of the pole, and of the height of the Sun.
