Question

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

Answer 1

Answer:

Constructive interference  

Explanation:

In this case, Pierce conducts an experiment in which waves collide in a way that the energy increases. This is the case of constructive interference.  

In constructive interference, the amplitudes of two waves adds up. We know that the energy is directly proportional to the square of the amplitude. So, as a result, the energy increases.

Hence, the correct option is (c) " constructive interference "

Answer 2

The best and most correct answer among the choices provided by the question is the third choice. What he observed on the waves is the constructive interference. I hope my answer has come to your help. God bless and have a nice day ahead!
