The prediction about the waves if they were to crash into each other is that The resulting wave would travel at 4.2 hertz.
<h3>What is the wave about?</h3>
Note that:
Constructive interference of the waves is one that leads to an increase in amplitude or frequency of any kind of waves.
Hence:
F' = 3 Hz + 1.2 Hz
= 4.2 Hz
Destructive interference of the waves is one that lowers the amplitude or frequency of waves and as such:
F' = 3 Hz - 1.2Hz = 1.8 Hz
The prediction about the waves if they were to crash into each other is that The resulting wave would travel at 4.2 hertz.
