Due to constructive interference, we can predict that: C. the resulting wave would travel at 4.2 hertz.
<h3>What is constructive interference?</h3>
Constructive interference of a wave can be defined as a phenomenon through which two waves of the same frequency and phase combines to form a wave of higher magnitude.
This ultimately implies that, the constructive interference of a wave causes an increase in the amplitude or frequency of waves.
Due to constructive interference, we would have:
Wave = 3 + 1.2
Wave = 4.2 hertz.
