Watch which works on the phenomenon of the shadow formation
Answers
Answer:
Shadow is nothing but space when the light is blocked by an opaque object. It is just that part where light does not reach. When you stand in the sun, you are able to see your shadow behind you.
How do you see that shadow? This is because our body is opaque and does not allow the light to pass through it. This is how the shadow is formed behind us. When you go to a party, you wear a colorful dress. But when you look at your shadow can you see the colors? NO! We always get a black shadow.
Formation of Shadows
To form a shadow a source of light is required. It is only when light rays are obstructed we get the shadow of the object. The size of the shadow keeps on changing with the position of the sun. Shadows are always formed on the opposite side. Transparent objects cannot form a shadow. They are only formed in opaque or translucent objects. If we take a glass slab, no shadow is formed because it allows light to pass through it.
Types of Shadows
It is not necessary that the shape of the shadows will be identical to the shape of the object. The shape of the shadow depends on the direction of light falling on it. Here we can see the shadow of the car as a rectangle because maybe the shadow is falling from the top of the car.
