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.

Why did the lunar eclipse have the shadow begin at the top?
That was because of the angle of the sun shining on the Earth and casting a shadow on the moon from your perspective. From Australia, the shadow started at the bottom and moved upwards, even though we were all looking at the same moon at almost the same time.
Has the cross of Jesus ever appeared on your wall?
It was a shadow caused by the angle of light shining onto the wall, nothing more.
What is the definition of shadow angle?
the angle at which a shadow is formed
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?
is that the entire question because you already gave the angle, meaning you now have every angle for the triangle created by the pole and shadow
How do shadows change and what makes them change?
I'm pretty sure that... Shadows change when the angle of light shining on the object changes. Eg. A person standing in the sun just as it rises will have a longer shadow facing west because of the angle that the sun is at. Whereas the same person standing in the same spot at midday will have a shorter Shadow so the shadow will make the person look shorter. If the light (sun) is directly on top of the person, they mah have no shaddow.
What is a shadow angle?
an angle (that can be on the earth) at which an angle could be formed by the sun.
Are your shadows short at sunset?
No. Because of the angle of the sun, your shadow will be longest at when the sun is rising or setting. It is shortest at noon, when your shadow is directly under you.
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
When a light is close to n object the shadow formed is big because?
The angle of the light passed the edge of the object is greater, creating a larger shadow.
When light hits something opaque we get a shadow so why do we have almost no shadow when the sun is high and there seems to be more light?
Because the Shadow is also dependent on the angle of the light source compared to the opaque 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.
What is the measure of the tangent angle that the rays of the sun make with horizontal if a street post standing vertically on a level surface casts a shadow of 6 meters?
inverse of tan(h/6). where h=height of street post in meters.
