Question

Which of the following statement is true regarding the shape of a shadow?

• A. It is always similar to the object.
• B. It depends on the orientation of light source and the size of the object.
• C. It is always smaller than the object.
• D. It is always larger than the object.

Answer 1

The correct option is B

It depends on the orientation of light source and the size of the object.

The shape of a shadow depends on the shape of the object and on the orientation of the source of light with respect to the object. For example, the shadow of a cube can be rhombus, square or rectangle depending on the orientation of source of light. In addition, the size will depend upon the distance between the object and the source of light.
