How does an object cast different shadows of different shapes?
If the object was a regular shape (a cube for example) it would cast the same shadow from any angle. An irregular shape (such as a car) will cast different shadows dependent upon the source of the light.
A vertical pole 5 feet long casts a shadow of 2 feet if at the same time a nearby tree casts a shadow of 10 feet how tall is the tree?
The tree is 25 feet tall. A 5 foot pole cast a 2 foot shadow. This means that the sun angle causes the shadow to be 2/5 the length of the object casting it. The tree's shadow is 10 feet tall. Multiply 10 feet by 5/2 (inverting the fraction because we're going the other way) and we get 25 feet.
When the shadow cast by a 1.2 m fence post was 1.8mthe shadow cast by a pine tree was 27.6m and by an oak tree was 45m.How tall was each tree?
There are similar triangles with the shadows as one side, the objects as another and the sun's rays as the third. The ratio of height to shadow is 1.2m : 1.8m = 1.2 : 1.8 = 2 : 3 Therefore to convert shadow length to height divide by 3 and multiply by 2, which is the same as multiplying by 2/3 → height pine = 2/3 × 27.6 m = 18.4 m → height oak = 2/3 × 45 m = 30 m
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
When a tree cast a 20 foot shadow a man 6 feet tall casts a 3 foot shadow how tall is the tree?
The man is twice as high as his shadow. Therefore, the tree must also be twice as high as its shadow, which would make the tree 40 feet tall.
How does the position of the sun in the sky relate to the length of the shadow cast by an object?
The position of the sun in the sky directly affects the length of the shadow cast by an object. When the sun is higher in the sky, shadows are shorter, and when the sun is lower, shadows are longer. This is because the angle of the sun's rays hitting the object changes throughout the day, affecting the length of the shadow.
Is the shadow longer behind an object?
Yes, the shadow is longer behind an object, as it is cast by the object blocking the light source. The length of the shadow will depend on the angle and position of the light source in relation to the object.
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 in feet would the shadow be for an object which is 18.6 feet tall?
In addition to the height of the object, the length of its shadow depends on a few other things that are not described in the question. -- Is the object standing straight upright ? -- Is the shadow cast on the ground or on sometheing else? -- If on the ground, is the ground level ? -- What is the altitude (angle) of the sun ?
What is the relationship between the size of the shadow and the distance of the object from the light source?
The relationship between the size of a shadow of an object and the distance of light source from the object is indirectly proportional. A short distance will make the shadow big while making the distance long will reduce the size of the shadow.
What does shadow cast by heavenly bodies is called?
When the shadow is cast on another object it is called an eclipse.
What is one object in space casting a shadow on another?
A shadow cast on one object in space on another is ECLIPSE
What time would a shadow be at its longest?
That depends where you are on the planet. Your shadow would be longest if you were standing on a rotational pole at the time of equinox. At this point your shadow would be infinity long as it would be "projected" into space. However as a rule of thumb one's shadow is longest when the sun is rising or setting but high enough to cast your shadow.
What do you call the object that do not cast a shadow?
ground ot
What three things are needed to cast a shadow?
To cast a shadow, three things are needed: a source of light, an object to block the light, and a surface for the shadow to be projected onto.
What determines the shape of a shadow?
The shape of a shadow is determined by the direction of the light source and the object casting the shadow. The angle of the light and the distance between the object and the surface onto which the shadow is cast also play a role in shaping the shadow.
Does an opaque object cast a shadow?
Yes, an opaque object blocks light, creating a shadow behind it. The shadow is the area where light is obstructed from reaching, resulting in a darker region.
