Question

Pierce conducts an experiment in which waves collide in a way that the energy increases, which means that has occurred

Answer 1

Answer:

It means the waves collides and constructive interference occurred.

Explanation:

If the two waves coming from the opposite direction collide with each other, there are two way of their interference.

• Constructive interference: An interference which results in the increase in energy. And it is when crust of a wave comes on the crust of second wave.
• Destructive interference: An interference which results in decrease in energy of the resulting wave and colliding waves cancel the result of each other.

Hence in experiment there will be constructive interference.

Answer 2

It seems that you have missed the given options for the given statement above. But anyway, here is the correct answer. Pierce conducts an experiment in which waves collide in a way that the energy increases, which means that CONSTRUCTIVE has occurred. Hope this is the answer that you are looking for.
