Let us Talk

AHave you seen your own shadow or the shadow of a tree, a dog, a cow or any other animal?Show solution
Yes! We can see the shadow of our own body, a tree, a dog, a cow, and many other animals and objects around us. A shadow is formed when an object blocks light.

BWhen do we see a shadow?Show solution
We see a shadow when there is a source of light (like the Sun or a torch) and an object comes in the path of that light. The object blocks the light and a dark shape — called a shadow — is formed behind it.

CWhen does a shadow vanish?Show solution
A shadow vanishes when there is no light, i.e., in complete darkness, or when the object is removed from the path of light. For example, at night without any light source, we cannot see shadows.

Fun with Shadows

AWill the size of shadows change on changing the position of the torch?Show solution
Yes, the size of the shadow changes when we change the position of the torch.
- When the torch is held very close to the object, the shadow becomes bigger (larger).
- When the torch is moved farther away from the object, the shadow becomes smaller.
- The angle of the torch also changes the shape and length of the shadow.

BAt what time of the day is your shadow longest?Show solution
Our shadow is longest in the early morning (just after sunrise) and in the late evening (just before sunset). This is because the Sun is at a low angle in the sky at these times, so the shadow stretches out very long.

CAt what time of the day is your shadow shortest?Show solution
Our shadow is shortest at noon (around 12 o'clock in the afternoon). This is because the Sun is directly overhead at noon, so the shadow falls almost directly below us and appears very short.
