[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.
midday
longest
Yes. The afternoon is directly after midday.
It depends on the time of day because the angle of the sun will determine the shadow length
The shadow of the tree would be shortest at midday when the sun is directly overhead. This is because the angle of the sunlight is most perpendicular to the tree, resulting in a shorter shadow. At sunrise and sunset, the angle of the sunlight is lower, creating longer shadows.
At midday your shadow will be at its shortest as the sun is closer to being overhead and you block less of its light. As the afternoon progresses and it gets further past midday the sun sinks lower in the sky and your shadow gets longer.
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.
The shortest shadow on a sundial would be afternoon or Middaay
Midday because the sun is right above you.
A shadow.
Yes - it's simple trigonomety - the shadow length (assuming level ground, the sun at angle a and a vertical object of height h) is h tan a, where a = 0 at midday with the sun directly overhead.
That largely depends on whether or not the sun is up. If the sun is still out a 9pm, a shadow is much longer, then.
That depends on how big the object is, the time of year, and the location you are. obviously, the size would make a difference, the season determines the tilt of the earth changing the shadow length. if you were in Africa at midday, your shadow would be short since the sun is directly overhead. if you were in Antarctica at noon, the sun would be lower to the ground thus creating a longer shadow.
i think its to do with the sun, when the sun moves the size of your shadow moves. at midday its the shortest :))
A shadow. It is smaller at midday when the sun is directly overhead, and longer in the late afternoon as the sun starts to set.
