Investigating How the Size of a Shadow Depends on the Angle at Which the Light Hits the Object

Purpose ============ Depending on the size of the investigation shadow of the light hitting the object at the project's point of view, then carefully refer to how it changes the shadow, one of the factors The size of the shadow is observed to have influenced factors influencing the size of the observation. Variables that may affect shadow size ======================================= ============= ==== However, we examine how the factor affects the size of the shadow. Other factors can also be considered.

The size of the shadow depends on the angle at which the light strikes the object. Your shadow is changing all day. Is it the longest in the morning and evening? There is little shadow at noon when the sun is overhead. why? Therefore, changing the angle of light and changing the position of the sun all day falls to the ground. Long ago, the shadow people of the track of the length of the day keep track of the time. The earliest clock in the world is the sun's clock.

Shadows have different sizes. Small people make small shadows. A huge building is a big shadow. The position of the sun affects the size of the shadow. If the sun is low in the sky, the experience of people and things will block more light. The more light, the longer the light will be. When the sun rises in the sky, light is blocked. This will shorten the shadow. Shadows also exist in the universe. NASA's explorer messenger is Mercury's research. Mercury is the nearest planet to the sun. Scientists want to build MESSENGER to make sure it does not get too hot. Therefore, they use a large fabric covering the sun-lit side. This cloth is called a "parasol". I feel like a hard cloth. I shadow the sun's light and make a shadow. This shadow keeps the spaceship cooler
