Answer 1

Ответ:

Вечером и утром тени длинные. В полдень тени короткие. Длина тени зависит от угла между предметом и лучем света, падающего на этот предмет. Чем больше угол, тем длиннее тень, соответственно, и наоборот.

The Length of Shadows and Factors Affecting Their Size

Shadows are formed when an object blocks the path of light. The size of a shadow can vary depending on several factors, including the time of day, the position of the sun, the size of the object, and the distance between the object and the light source.

The Longest Shadows: The longest shadows are typically seen during the early morning or late afternoon when the sun is low on the horizon. This is because the angle at which the sunlight reaches the Earth's surface is more oblique, causing objects to cast longer shadows. In contrast, during midday when the sun is directly overhead, shadows tend to be shorter.

The Shortest Shadows: The shortest shadows are observed when the sun is at its highest point in the sky, around noon. At this time, the sun is directly overhead, and objects cast shorter shadows due to the more vertical angle of the sunlight.

Factors Affecting Shadow Size: The size of a shadow is influenced by various factors:

1. Time of Day: Shadows change in length and direction as the position of the sun changes throughout the day. 2. Sun's Position: The angle at which sunlight reaches the Earth affects the length and direction of shadows. When the sun is low on the horizon, shadows are longer, while they are shorter when the sun is higher in the sky. 3. Object's Size: The size of the object casting the shadow also affects the length of the shadow. Larger objects tend to cast longer shadows compared to smaller objects. 4. Distance Between Object and Light Source: The distance between the object and the light source, such as the sun, also plays a role in shadow size. Objects closer to the light source may cast larger shadows compared to objects farther away.

Conducting Shadow Size Comparisons

To conduct your shadow size comparisons, you can follow these two experiments:

1. Measuring and Comparing Shadows of the Same Object at Different Times of the Day: Choose an object and measure its shadow length at different times of the day, such as early morning, noon, and late afternoon. Record the measurements and compare the lengths of the shadows. You will likely observe that the shadow is longest in the early morning or late afternoon and shortest around noon. 2. Measuring and Comparing Shadows of the Same Object at the Same Time of Day, but on Different Days: Select a specific time of day, such as noon, and measure the shadow length of the same object on different days. Record the measurements and compare the lengths of the shadows. You may notice variations in shadow length due to changes in the sun's position throughout the year.

Remember to exercise caution when conducting experiments involving sunlight and shadows. Ensure your safety and avoid looking directly at the sun.
