you observe?
2.With the help of suitable diagrams, show that the size of shadow formed,
depends upon the relative position of the source and the opaque object.​

Answer 1

Answer:

If the face of torch is covered with transparent colored paper and the beam sent through an opaque object, the opaque object since does not reflect light will only observe a kind of dark shadow behind the object, Thus, a shadow is formed when light is made to pass through it.
