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 will be the height of the shadow cast by a person standing near a 20 ft light post.The height of the person is 6 ftThe distance between man and pole is 10 ft?
It is zero: 0cm; 0mm A shadow has no height: length yes, but height no
What is the height of the shadow when the distance from the object to the screen is 60 cm ............................?

What tool do you use to measure the height of a school?
(1) One way would be to have a stick, stuck vertically into the ground. Measure the length of the shadow and the length of the stick. The actual height of the stick will be a ratio of the shadow's length. Then measure the length of the school's shadow. The height of the school in comparison with its shadow length will be same ratio as the height of the stick compared to its shadow length. You could use a tape measure for this. And possibly a calculator, which will make the calculation easier than doing it by long arithmetic or mental arithmetic. (2) Another way would be to use something that can tell you, from a short distance away from the school, the angle between the top of the school and the ground. A sextant can do this. It is more accurate than using a protractor. Using trigonometry and the distance from the building to where you are standing, you will be able to calculate the height of the school, because it will be at right angles to the line from you to the school. If you don't know trigonometry, method (1) will be easier.
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.
What is the height of a building that cast a 105' shadow when a 6' man casts a 14' shadow?
Height of building/105 = 6/14 Multiply both sides by 105: Height = 630/14 Height = 45 feet

What is the height of the shadow when the distance from the light source to object is 24cm?
The height of the shadow would be the same as the object's height if the light source was directly above the object. If the distance from the light source to the object is 24cm, the shadow's height would depend on the angle of the light source to the object and the height of the object.
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.
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.

Measure the height of building 6 ft pole in shadow of building and covers shadow of building distance between pole and building 182ft pole cast shadow of 5.25ft how tall is building?
208 ft pole
Can you tell the time using your shadow?
Yes, you can estimate the time of day by the length and direction of your shadow. In the morning, the shadow will be longer, pointing towards the west, and in the afternoon, the shadow will be shorter, pointing towards the east. This method is not as precise as using a clock, but it can give you a rough idea of the time.
What is the Height of Shadow the hedgehog?
3'6"
Is your shadow always the same height?
NO.
Describe three factors that determine the size of a shadow and explain how each one cam make the shadow larger or smaller?
The height of the object casting the shadow, the height of the sun in the sky, what angle you are at when looking at the shadow.
How many distance move a shadow in one hour?
The direction a shadow points turns 15 degrees in one hour. The distance the end of the shadow moves depends on the length of the shadow.
