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.
When during the day should you look for your shadow?
You should look for your shadow when the sun is shining at its peak, around midday. This is when the sun is highest in the sky, causing your shadow to be the shortest.
Why does a shadow Change depending on the time of day?
The shadow is cast by the sun.As the earth rotates on it's axis, the sun appears to move across the sky in an arc.The height and direction of the sun is constantly changing throughout the day and so the shadow will also change. When the sun is high the shadow is short. When the sun is low, the shadow will be long.
How did sundials help people tell time?
Sundials use the position of the sun to cast a shadow onto marked surfaces, indicating the time of day based on the shadow's position. By following the movement of the shadow, people could estimate the time accurately during daylight hours. Sundials were widely used before the invention of mechanical clocks and provided a simple and reliable method for telling time.
What type of clock called which uses a shadow to tell time?
A clock that uses a shadow to tell time is called a sundial. It consists of a flat plate marked with hours and a gnomon (a vertical post) that casts a shadow on the plate. As the sun moves across the sky, the position of the shadow indicates the time of day. Sundials rely on sunlight, making them most effective during clear days.
A yard stick casts a shadow that is 24in longA street sign at the same time cast a shadow that is 72in longwhat is the height of the street sign?
3 yards in height
Is shadow length same during any time of the day?
no
How is a tree that casts a 28-ft shadow at the same time a 4-ft pole casts a shadow which is 9-ft long?
The height of the tree is in direct proportion to the pole and its shadow
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 high is a tree that's casts a ft shadow at the same time a ft pole casts a shadow which is ft long?
To determine the height of the tree based on the shadow length, we can use the concept of similar triangles. If the tree casts a shadow of 1 foot while a 1-foot pole also casts a shadow of 1 foot, then the height of the tree is the same as the height of the pole. Thus, the tree is also 1 foot tall.
How tall is a tree that casts a 30 ft shadow at the same time an 18 ft pole casts a shadow that is 6 feet long?
It is 90 feet in height
If you're 5 ft 3 inches tall how tall would your shadow be in inches?
It's not possible to give you an answer without knowing the height of your shadow, because the height of a shadow depends on the position of the light (the lower the longer the shadow is). But if the shadow is exactly the same height as you, it would be the same inches in height as you are. To calculate that, just multiply 5 ft x 12, which = 60 inches, then add the other 3 inches to it. That would give you a total of 63 inches.
How high is a tree that casts a 37 ft shadow at the same time a 4foot pole casts a 12 foot shadow?
It works out as 12 feet and 4 inches in height
A young man 150 cm tall cast a shadow that was 200 cm long his father's shadow cast at the same time of day was 240 cm long how tall was his father?
The ratio of the young man's height to his shadow is 150:200 or 3:4 The ratio for the father is the same. His shadow is 240 cm so his actual height is 240*3/4 = 180 cm
A tree cast a 24-foot shadow at the same time a fence post 5 feet high cast a 4-foot shadow how tall is the tree?
It works out as 30 feet in height
At a certain time of day a person 6 feet tall casts a 4-foot shadow How long is the shadow cast by a 21-foot tree at the same time?
Designate the unknown shadow length by s. Shadows cast at the same time and place are proportional to the height of the object casing the shadow. Therefore: 4/6 = s/21, or s = [4(21)]/6 = 14 feet.
How long can a shadow be at ten zero zero am?
The answer depends on: 1. your latitude 2. The time of year 3. The time of day 4. The angle of the sun 5. The height of your object that casts a shadow Note: zero zero am is 2400 hours (military time) or 12:00 am (night time in most locations during most of the year). During some part of the year at the poles, the sun never sets or never rises. When the sun never rises or it is dark, there will be no shadow. When the sun is present, the shadow of an object depends on the angle of the sunlight & the height of the object.
