Question

A water wave approaches a wall with a small hole in it. The wave is blocked by the wall, except for the part that goes through the hole. The waves coming out of the hole begin to spread out as the new source of wavefronts. This is an example of what property?

a Interference
b Amplitude
c Collision
d Diffraction​

Answer 1

d. Diffraction.

Step-by-step explanation:

Diffraction is the bending of waves around obstacles or through openings.

In the given question, the water wave is diffracted as it passes through the hole in the wall.

This means that the wave bends and spreads out on the other side of the hole.

So, the answer is d. Diffraction.

The other answer choices are not correct:

• Interference is the interaction of two or more waves when they meet.
• Amplitude is the height of a wave.
• Collision is the interaction of two or more objects when they hit each other.
