How do you measure height by shadow?
How do you measure height by shadow?
Multiply the length of the tree’s shadow by your height, and then divide the resulting number by the length of your shadow. For example, if you are 5 feet tall, your shadow is 8 feet long, and the tree’s shadow is 100 feet long, the height of the tree is (100 x 5) / 8 = 62.5 feet.
Is the shadow the hypotenuse?
The length of the shadow is the base of the triangle, the height of the man is the height of the triangle, and the length from the tip of the shadow to top of the man’s head is the hypotenuse.
How do you calculate area of a shadow?
If the candle is placed at the center of the top surface, let the distance from the origin (center of the surface) to the end of the shadow be r. In this case the area of the shadow can easily be calculated by the difference of 2 circular areas ie:- πr2− Area of cylinder’s base.
What is the distance from the top of the light pole to the end of its shadow?
19.31 feet
The distance from the top of the light pole to the top of it’s shadow is 19.31 feet. Process of Elimination Hint: You can immediate eliminate 2 answers based on the properties of right triangles.
How can this difference in the length of your shadow be explained?
The explanation is partial. If you go outside on a sunny day, you will make a shadow. At some times of day your shadow is longer than you are. Scorer Comments: Student response explains that the rotation of the Earth causes the Sun’s light to hit the Earth at different angles, affecting the length of the shadows.
How do you measure the height of a flagpole shadow?
Measure the length of the shadow of the yardstick and the flagpole. Since the ends of the shadows are in line with the tops of the respective objects and the sun, the lengths of their shadows are proportional. Multiply the shadow ratio by the height of the yardstick (yh) to get the height of the flagpole.
What is the length of the shadow?
The length of shadow to your height is proportional to 1/Tangent (sun’s altitude). If the sun is low in the sky (10 degrees), your shadow would be 5.67 times as long as your height. The corresponding ratio at 5 degrees is 11.43 . (So an average height person (5.8 feet) would have a 66 foot long shadow).
