In therory, infinitely long. In practice, the shadow will fade into dispersed light.
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.
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.
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
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
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.
The position of the sun relates to the length of the shadow cast by an object because, when the sun is above the object there is no shadow yet, when the sun is say to the east of the object a shadow is cast towards the west, the farther the sun for example east the longer the shadow will be towards the west.
For a given shadow object, and at a given time of the day, the shadows will be longer in winter, for then the Sun will be lowest in the sky
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.
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 ?
yes it dose cast a shadow because you can not see through it.
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.
When the shadow is cast on another object it is called an eclipse.
A shadow cast on one object in space on another is ECLIPSE
The shadow that is casted by one object in space on another is called an Eclipse.

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.
As can be observed on any sunny day, the shadows are longest at sunrise and at sunset.
