What is the length of the shadow at midday?
It's determined by the height (angle above the horizon) of the Sun, and the physical height of the object throwing the shadow. The height of the Sun at midday is 90 degrees minus the latitude plus the Sun's declination of the day, which varies by up to ±23.5 degrees through the year. The length of the shadow is the height of the object divided by the tangent of the Sun's height. Example, a 6 ft object at 50 degrees north on June 21: height of the object is 6 ft, divided by tan(90 - 50 + 23.5) so the shadow has a length of 3 ft.
