When is the shadow equal in length to your height?
When the angle of elevation equals 45 degrees. tan-1(1) = 45 degrees.
A flagpole casts a ten meter shadow at the same time as a six meter statue beside it casts a two meter shadow What is the height of the flagpole?
The statue is 6/2 = 3 times the length of its shadow. The flagpole is 3 times its shadow ie the flagpole is 3*10 = 30 metres.
Are shadows longer or shorter than your actual height?
it depends on where the sun is in the sky If the sun is at its highest point ur hsadows will be shorter but as the sun get slower your shadow will get longer
A vertical yardstick casts a 1 foot shadow and the same tree nearby casts a 15 foot shadow How tall is the tree?
That depends on the height of the yardstick whose height has not been given.
A tree cast a 9 ft shadow at the same time that the a person 6ft tall cast a 4 ft shadow what is the height if the tree?
To find the height of the tree, we can set up a proportion using the similar triangles formed by the tree and its shadow, and the person and their shadow. The ratio of the height of the tree to its shadow is the same as the ratio of the height of the person to their shadow. This gives us (height of tree)/(9 ft) = (6 ft)/(4 ft). Solving for the height of the tree, we get height of tree = (9 ft * 6 ft) / 4 ft = 13.5 ft.
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.
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.
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.
How tall is the arch if a boy is 5 feet tall and stands under the Gateway Arch in St Louis and casts a shadow that is 1 foot long and the shadow of the Arch is 126 feet long?
To find the height of the Gateway Arch, we can use the concept of similar triangles. The ratio of the boy's height to his shadow length is the same as the ratio of the Arch's height to its shadow length. Therefore, if the boy is 5 feet tall and casts a 1-foot shadow, the height of the Arch can be calculated as follows: Height of Arch = (Height of boy / Length of boy's shadow) × Length of Arch's shadow = (5 feet / 1 foot) × 126 feet = 630 feet. Thus, the Gateway Arch is 630 feet tall.
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.
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 do you measure wood size?
By its shadow :) Then I measure mine shadow, or shadow of any object I know how high is.. and use proportion: HW/MH=WS/MS or HW=MH x WS/MS HW=wood height MH=mine height WS=length of wood shadow MS=length of mine shadow
What will be the shadow length at 4 pm?
The answer depends on: the height of the item casting the shadow, the location on earth, the time of year, and the inclination of the surface on which the shadow is cast.
I have no idea how to go about this question on my geometry homework! Can someone help me?
The two triangles shown are similar triangles. Numerically, the ratio computed by dividing the length of any side of tower triangle by the length of the corresponding side of the walking stick (similar) triangle will be the same value. Therefore, when the length of the tower shadow is divided by the length of the walking stick shadow, that ratio will be the exactly same as the tower height divided by the walking stick height. (length of tower shadow)/(length of walking stick shadow) = (tower's height)/(walking stick height) tower's height = {(length of tower shadow)/(length of walking stick shadow)}*(walking stick height)
How can you find the height of tree?
Using trigonometery if you know the length of its shadow and angle of elevation
Does the height of a light source affect the length of a shadow?
Yes, the height of a light source affects the length of a shadow. When a light source is higher, it casts shorter shadows, as the angle of light is more direct. Conversely, if the light source is lower, shadows tend to be longer due to a shallower angle of incidence. Thus, the relationship between the height of the light source and shadow length is inversely proportional.
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.
