Respuesta :
A shadow forms on the side of an object that faces away from the sun. The length of shadows changes as Earth rotates. In the morning, the sun is low in the eastern sky and shadows are long. As time passes in the morning, the sun seems to move higher in the sky.
The size of the object changes with change in the position of the light source.The length of the shadow of the object decreases as the sun position changes from down to top in the sky.
Sunlight
Sunlight has the sun rays. This rays travel to the earth. When the sun rays reach to earth they hit the object comes in his way. If the sun rays hit the opaque body ( a body that absorb some light when light fall on it) the light can not pass through them and the shadow appears.
What is the affect pf sun's position on the length of shadows?
The shape of a object determine the shape of the shadow made by him but the size of the object does not depends on the size of the object.
The size of the object changes with change in the position of the light source.The shadow appears in the opposite direction from where the sunlight falls on body.
At the outdoor, when there is sun in the sky, the size of the shadow is different at different sun position on the sky.
- At the time of morning the sun is in the east direction low level at sky. At this position the sun rays passes through the objects vertically. It results in the long shadow of the object in the west direction.
- At the time of noon the sun is at top of the sky. The sun rays fall on a object vertically. The shadow made by the object is smaller or nothing as the opposite surface is grounded. Thus in the noon time the shadow length is smaller.
- At the time of evening the sun is again down in the sky. The sun rays falls vertically, Hence the shadows made by the object is longer and in the east direction.
Hence the length of the shadow of the object decreases as the sun position changes from down to top in the sky.
