What happens to shadows in moonlight and light?

The change of shadow depends on the position and intensity of light source and the shape and size of object.

In the moonlight, the length and shape of the shadow will change with the position and angle of the moon. When the moon is high in the sky, the shadow will be longer and clearer; When the moon is near the horizon, the shadow will be short and fuzzy. In addition, the brightness of the moon will also affect the brightness of the shadow. At the full moon, the shadow is relatively dark, while at the new moon, the shadow is almost invisible.

In light, the length and shape of the shadow also depend on the position and intensity of the light source. If the light source is directly above, such as under a street lamp, the length of the shadow will be shorter and wider; If the light source is located on the side, such as under the window light, the length of the shadow will be longer and narrower. In addition, if the intensity of the light source increases, such as in a spotlight, the shadows will darken and lose details.

In the sun, the length and shape of the shadow will also change with the position and angle of the sun. At sunrise and sunset, the sun is low, the light is soft, and the shadow will be long and fuzzy; At noon, the sun is higher, the light is stronger and the shadow is shorter and clearer. In addition, the shadows in the sun are usually brighter than those in the moonlight, because the intensity of sunlight is higher.

In short, the position and intensity of the light source, the shape and size of the object, and the observation angle will all affect the change of the shadow. Under different light sources and different environmental conditions, shadows will have different forms of expression.
