Detailed Solution

The length of the shadow will be longest when the light source and the object are perpendicular to each other.
The longest shadows of the day are cast at sunrise and sunset because they are at the most extreme angles before the sun is obscured by the horizon. That's why we can see the longest shadow in real life at sunrise or sunset.
The shortest shadow of the day will be cast at noon, although the exact length will depend on the time of year and how far the object is from the equator. Since the sun never rises directly overhead, the length of the shadow increases with distance from the equator.
