Jerimiah is studying Wave A and Wave B. Wave A is traveling at 3 hertz, and Wave B is traveling at 1.2 hertz.
Inga [223]

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.

What happens if you don't pay your insurance premium for your car?\
kondaur [170]
Well, technically, you don't need insurance to drive a car. However, it is very important, and highly recommended. If you're vehicle happens to be stolen, or destroyed in any way, you have to pay for the issue out-of-pocket. That would really hurt bad financially, so without paying insurance, you're at a large risk.
