How do shadows appear?

Shadows are made by blocking light. … If an opaque (solid) object gets in the way, it stops light rays from traveling through it. This results in an area of darkness appearing behind the object. The dark area is called a shadow.

In which part of the day you observe the shortest shadow?

Noon is going to produce the shortest shadow of the day, though this length will vary based on the time of year and how far north (or south) of the equator you are. The further away from the equator, the longer the shadow, because the sun will never reach directly overhead.

At what time shadow is longest?

Shadows are longest in the early morning and late afternoon/early evening when the sun appears low in the sky. As the Earth rotates on its axis, the sun hits each location in the morning at an angle. This becomes more vertical as the sun appears to pass more directly overhead around noon.

What direction do shadows face in the morning?

The sun always rises in the east and sets in the west, but not exactly due east or due west. There is also some seasonal variation. Shadows will move in the opposite direction of the sun. In the Northern Hemisphere, they will move from west to east, and will point north at noon.
