Question
When describing water waves passing around an obstacle in a ripple tank, what is meant by the
obstacle's "shadow"? (1 point)
The area directly in front of the object where waves are obstructed from passage
A region behind the obstacle as wide as the obstacle and extending to the end of the tank
Any dark bands observed in the interference pattern
The area directly behind the object where diffracting waves have not yet reformed the wavefronts

The correct answer is:
**The area directly behind the object where diffracting waves have not yet reformed the wavefronts.**
In this context, the "shadow" refers to the region directly behind the obstacle where the wavefronts have not yet recovered from being blocked and the effects of diffraction.
**The area directly behind the object where diffracting waves have not yet reformed the wavefronts.**
In this context, the "shadow" refers to the region directly behind the obstacle where the wavefronts have not yet recovered from being blocked and the effects of diffraction.
