How could you measure the height of a tree at noon when the sun is directly overhead and the tree casts no shadow?
Your best bet here would be to use trigonometry. One stand a given distance away from the tree and sight the top of the tree, say with a clinometer, to measure the angle of elevation. Then knowing the angle and the distance you are from the tree, the height of the tree can be calculated with a tangent function.
What else can I help you with?
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.
A building with height D feet has a shadow with G feet as its length. What is the height of a neighboring building with a shadow of C feet?
D/G = x/C The x is the height of the neighboring building. Just cross-multiply, then divide.
What is the height of a tower if its shadow is 500 feet long and a flag pole is 40 feet tall with a shadow 36 feet long?
The ratio of the height of the object to its shadow are the same for both objects. So, if H is the height of the tower, then H/500 = 40/36 therefore H = 500*40/36 = 555.55... feet.
A tree casts a shadow that is 21 feet long at the same time as a fence post casts a shadow that is 6 feet long The fence post is 4 feet tall What is the height of the tree?
Ratio of object to its shadow is the same. So if T is the height of the tree, then T/21 = 4/6 So T = 21*4/6 = 84/6 = 14 feet
A 3 foot pole casts a 6 foot shadow A 4 foot pole casts an 8 foot shadow Use a linear equation to predict the length of a shadow cast by a 6 foot pole?
Shadow lengths are proportional to the heights of objects casting the shadows. Therefore, calling the shadow length l, the height h, and the proportionality constant k, l = kh. (The intercept is 0 because an object with no height casts no shadow.) Therefore, in this instance k = l/h = 6/3 or 8/4 = 2. then l(6) = 2 X 6 = 12 feet.
How long would my shadow be if i was 5'6?
Your height isn't as important as the time of day of the measurement. When the sun is directly overhead, your shadow won't be measurable.
Why do we cast hardly any shadow in the middle of the day?
Because the sun is directly overhead.
When is the shortest shadow cast?
The shortest shadow is cast at noon when the sun is directly overhead, resulting in the smallest angle of incidence for sunlight and the shortest shadow length.
What time during the day is your shadow the same height as you?
Both. At sunrise and sunset on a sunny day, your shadow will be very long. As the sun rises and approaches it's zenith at noon, your shadow becomes progessively shorter, then lengthens again throughout the afternoon.
What time of day is the shadow shortest?
Noon, because the sun is directly overhead.
What does it mean when your shadow doesn't appear?
A shadow always appears. If you are solid, you create a shadow. If the light source is directly overhead, your shadow may be cast behind you. Just turn your head, and I assure you, your shadow will be there.
When is your shadow the shortest?
Your shadow is shortest when the sun is directly overhead, typically around noon on a clear day. This is because the angle of the sunlight is most perpendicular to your position, minimizing the length of your shadow.
What does it means if when you walk outside on a summer or winter day at noon and do not cast a shadow?
the sun is directly overhead.
When the sun is directly above you do you have a shadow?
No, when the sun is directly above us we don't have shadow. The shadow is under us. I disagree: Most people are bigger around at the hips than at the feet so you will have a shadow around your feet.
When the Sun is high in the afternoon how will be your shadow?
When the Sun is high in the afternoon, your shadow will be shorter and appear directly beneath you. This is because the angle of the Sun is more overhead, resulting in a shorter shadow length.
How does the position of the sun effect your shadow?
The position of the sun affects the length and direction of your shadow. When the sun is directly overhead (at its zenith), your shadow will be shortest and directly beneath you. As the sun moves lower in the sky, your shadow will lengthen and shift in direction depending on the angle of the sunlight.
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
