Shadow
[object Object]
By means of trigonometry if you know the angle of elevation or by comparing it with a nearby object if you know its height and shadow length.
In the direction opposite to that of the sun. It will be approximately West of the object but the exact direction will depend on the latitude and season.
The shadow is in front of you when the sun is behind you, typically in the late morning or early afternoon. The length and direction of the shadow will vary depending on the position of the sun in the sky.
longest
It will shorten as the sun rises to its apogee over the object casting the shadow.
When the sun rises in the morning, shadows will point towards the west. This is because the sun rises in the east and casts shadows in the opposite direction.
So long as the sun is the same height above the horizon your shadows will be the same length whether it is morning or evening.
The sun rises in the east, so shadow will fall to the west
The direction a shadow points turns 15 degrees in one hour. The distance the end of the shadow moves depends on the length of the shadow.
The length of a shadow is primarily determined by the angle of the sun in relation to the object casting the shadow. Shadows are longer in the early morning and late afternoon when the sun is lower in the sky, and shorter at midday when the sun is directly overhead. The size and shape of the object casting the shadow also play a role in determining shadow length.
It depends on the time of day, and, therefore, it depends on where the sun is in the sky.
Usually somewhere towards the west. However, the exact length and direction of the shadow depend on your exact geographical position (both latitude and longitude), and on the time of year.
By observing the direction and length of your shadow, you can determine the approximate position of the Sun. If your shadow is directly under you, it means the Sun is directly above you (at solar noon). If your shadow is longer and pointing towards the east, it means the Sun is in the west.
Morning shadows are longer and more stretched out because the sun is low on the horizon, casting shadows in a longer direction. Afternoon shadows are shorter and more concentrated because the sun is higher in the sky, resulting in shorter shadows cast in a more concentrated area.
