Answer 2

Shadows are formed in the following way -

• Our eyes can see the objects in the presence of the light and in the absence of the light,the darkness is created.

• Similarly,light can pass through transparent or translucent mediums but light cannot pass through opaque mediums.

• When opaque or partially opaque objects gets in the way of light rays ,the partial light rays are blocked by that object and a region of darkness which is similar to the shape of the original object is created behind the object.

This region of darkness is known as the shadow.
