What is the definition of shadow angle?
the angle at which a shadow is formed
About how long is a shadow of an 80 ft tall oak tree if the angle of the sun is 40 degrees?
It depends on the angle of depression of the sun. The answer would be 80ft * tan(90-angle of depression) At a depression angle of 40 degrees, the shadow would be 80 * tan (50) which equals 95.340ft
What is the measure of the angle between the end of the shadow and the vertical side of a 170ft building that cast a 40 ft long shadow?
Using trigonometry the angle of elevation is 77 degrees rounded to the nearest degree
At 11 am on January 13 If the length of the shadow is 2 m and 44 cm what is the Suns zenith angle?
The angle of the sun can be worked out through trigonometry, but first you will need the height of the object that is causing the shadow, since a taller object will make a longer shadow. Tan a = H/2.44 Where a is the angle and H is the height of the object. And the date is not relevant.
What is the height of the tree if it casts a shadow 146 feet long?
It depends on the time of day because the angle of the sun will determine the shadow length

What happens to a shadow if you change the angle at which light shines on an object?
The shadow will change in size and shape, becoming longer or shorter depending on the angle of the light. The direction of the shadow will also shift based on the angle of the light source relative to the object.
How does the surface behind a shadow affect the shape and size of an shadow?
If the shadow is on a convex surface, it will be bigger. On a concave surface it will be smaller. If the light source is at a low angle to the opaque object causing the shadow (e.g. you're casting a shadow from a flashlight behind you, to a sidewalk in front), the shadow will be relatively tall. If the angle of the light is high (e.g. sun nearly overhead), the shadow will be short. This will also depend on the angle of the shaded surface.
Does a street sign cast a shadow because light is shining on it at an angle?
An object casts a shadow whenever it is illuminated. It really has nothing to do with the angle. Regardless of the angle, it will cast a shadow. The LENGTH of the shadow it casts, however, is dependent upon the angle at which the light strikes the object. A stop sign will cast a very narrow shadow when the sun is directly overhead, for example, but will cast a very long one at sunrise or sunset.
How long is the shadow for the 74ft pole?
It depends on the angle of the sun. If the sun is at 90 degrees, immediately overhead, then the length of the shadow is 0. What is the angle of the sun?
Is your shadow bigger or smaller when you are nearer to the light source?
Your shadow is smaller when you are closer to the light source because the angle at which the light hits you creates a shorter shadow. As you move away from the light source, the angle of the light changes, resulting in a longer and larger shadow.
Suppose you know the height of a flagpole on the beach of the Chesapeake Bay and that you know the length of its shadow How do you calculate the angle of elevation?
If you also know its shadow then you can work out the angle of elevation
What does the size off the shadow depends upon?
The size of a shadow depends on the distance between the object blocking the light and the surface on which the shadow is cast, as well as the angle of the light source hitting the object. The closer the object is to the surface and the larger the angle of the light source, the larger the shadow will be.
How tall is a boy that casts a 4 ft shadow?
The height of a boy that casts a 4 foot long shadow depends on the angle of the sun. A tangent can be used to calculate his height if we know the angle of the sun using the equation: Height = shadow length x tangent of the angle of the sun. Using a calculator, it is easy to get the value of the tangent for any angle and then complete the equation.
What cause the different shape of a shadow?
The shape of a shadow is determined by the angle and position of the light source, the object casting the shadow, and the surface on which the shadow falls. Changes in any of these factors can alter the shape of the shadow.
How do you find the angle of elevation from the tip of the shadow of a 12 foot flag pole to the top of the pole is 60 degrees?
You can use trigonometry to find the angle of elevation. Let x be the distance from the tip of the shadow to the base of the pole and the height of the pole be y. Then, tan(60 degrees) = y/x. Given that the height of the pole is 12 feet, you can solve for x to find the angle of elevation.
Why does the length and position of my shadow changes as I walk towards and away from the lamp post?
The length and position of your shadow change as you walk towards or away from a lamp post because the angle of the light hitting you changes. When you are closer to the lamp post, the angle of the light hitting you is more direct, resulting in a longer shadow. As you move away, the angle becomes more oblique, shortening the shadow.
