Can somebody explain how to calculate the sun's angle in the sky at a certain time of day? It is wanted to calculate the length of an object by it's shadow.

The sun angle for an object's shadow can be calculated by using the length of the object's shadow and the height of the object. You can use the formula tan(θ) = shadow length/ object height, where θ is the sun angle.
Calculating the sun angle for an object's shadow can help determine the time of day and the position of the sun in the sky. It can also be used for navigation and tracking the movement of the sun over time.
The length of an object's shadow is usually measured in feet or meters. However, any unit of length can be used as long as it is consistent with the unit of measurement used for the object's height.
The accuracy of the sun angle calculation depends on the accuracy of the measurements taken for the object's shadow and height. The more precise the measurements, the more accurate the calculation will be.
Yes, there are many online tools and apps available that can calculate the sun angle for an object's shadow. These tools use your location and the current date and time to accurately calculate the sun angle. Some popular examples include SunCalc, Sun Position, and Sun Surveyor.
