ASP To Every Season There is a Reason
Height by shadow length. Sometimes, when designing antennas, the radio-hobbyist needs to find the height of some object, such as Telegraph pole, tall chimney, etc. The height of such object can be found using the theorem on the similarity of triangles and by direct measurements on the ground.... We’ll dive deeper into this in a minute, but to find the length of a shadow you can draw a line from the light source past the top of the object, and then another line from the Vanishing Point past the bottom of the object. Where those two lines intercect is the approximate shadow length, at least most of the time. We’ll talk about an exception to that rule when we get to Low Light sources
Why Do Shadows Change Length During the Day
the shadow has been traced, all members of the group should work together to measure the distance from the tape to the light source and make sure that this distance is written inside of the shadow tracing.... Every hour, on the hour, for 6 hours, starting at 9 am, use a pen to trace the length of the toothpick's shadow on the folder (e.g. 9:00AM, 10:00AM...). Label the time of day on the shadow. Measure and record the length of the shadow.

How To Find The Length Of A Shadow
In short: If you know length of shadow and object height (assuming vertical object casting shadow of an horizontal surface), you can tell time if you know date and you can tell date if you know time. If you know direction of shadow (e.g. relative to north) you can tell date and time without knowing any of them.
