The lower the sun is in the sky, the longer your shadow will appear on the ground before you. Therefore, a sunny dawn or just before sunset is the time of day for long shadows.
at noon time
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.
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
The shadow of an object on a flat horizontal surface starts out long , pointing west. As the day progresses the shadow shortens and in the Northern hemisphere moves north of the object becoming shortest and pointing due north when it is noon local solar time. The shadow lengthens and points more westerly later on in the afternoon.
Both. At sunrise and sunset on a sunny day, your shadow will be very long. As the sun rises and approaches it's zenith at noon, your shadow becomes progessively shorter, then lengthens again throughout the afternoon.
The only really practical usage I can think of is indicating the time on a Sun Dial. Thus the dial needs a fin-like shadow pointer called a Gnomon ( pronounced Nomon) The shadow is actually read off for the time of day.
The time of day in which you will hardly have any shadow is during 12:00PM or noon. This is because the sun is directly above you, casting little to no shadow.
the longest shadow you see in the day is 3\early in the morning and near the sunset...
Next time you go for a walk at night, walk under a streetlight, and watch your shadow on the ground. While you're watching your shadow, think about how the sun moves across the sky during the day.

Just as the sun rises in the morning and sets in the evening. It is then that the sun is at its lowest, so the shadows are longest, indeed infinitely so.
the sun casts a shadow onto the sundial and the shadow tells the time of the day.
