Answers & Comments
Answer:
1. At 8:00 am, the shadow of the pole would be relatively long as the sun is still low on the horizon. As it gets closer to noon, the shadow gradually becomes shorter. At 12:00 noon, the shadow would be at its shortest, possibly appearing directly beneath the pole. After noon, as the sun starts to move towards the west, the shadow begins to lengthen again. By 2:00 pm, the shadow would be longer compared to the shadow at noon but shorter compared to the morning.
2. The shadow of the pole is longest in the morning, around 8:00 am. This is because the sun is low on the horizon, causing the sunlight to hit the pole at a lower angle, resulting in a longer shadow.
3. The shadow of the pole is shortest at 12:00 noon when the sun is at its highest point in the sky. During this time, the sunlight is directly overhead, causing the pole's shadow to appear directly beneath it or very short.
4. Throughout the day, the position and length of the shadow of the pole change due to the movement of the sun across the sky. As the sun rises, the shadow becomes longer, reaching its maximum length in the morning. Then, as the sun moves towards noon, the shadow becomes shorter until it reaches its shortest length. After noon, as the sun starts to set, the shadow lengthens again.
5. The position of the shadow changes throughout the day due to the apparent movement of the sun across the sky. It moves from west to east, so the shadow moves in the opposite direction, starting from the west in the morning and shifting towards the east as the day progresses. The shadow does not stay in one place but moves as the sun moves.
6. If we continue to measure the shadow of the pole until the sun sets at 6:00 pm, the shadow would gradually lengthen as the sun moves lower in the sky towards the horizon. Eventually, when the sun sets, the pole would not form a visible shadow because there would be no direct sunlight illuminating it.
7. The changes in the position and length of shadows are directly related to the changes in the position of the sun. The sun's position in the sky affects the angle at which sunlight strikes objects, determining the length and direction of their shadows. As the sun rises, the shadow lengthens due to the lower angle of sunlight. At noon, when the sun is directly overhead, the shadow is shortest or nonexistent. Then, as the sun sets, the shadow lengthens again as the angle of sunlight decreases.
8. The activity implies that the position and length of shadows can be used as indicators of the time of day. Understanding how shadows change throughout the day can be helpful in daily activities at home, such as determining the best time for gardening or outdoor activities based on the position of the sun and shadows. It can also be relevant for optimizing natural lighting inside the house by considering the angle and direction of sunlight to maximize illumination and reduce the need for artificial lighting.
