In a physics mock, we were given a question in which there were two waves. One had a larger amplitude and frequency that the other. We were told to draw the resulting wave and from that work out the frequency and wavelength of the wave which is the result of the superposing of the two given waves.
To help put across my point I have modeled the waves using transformed sine graphs.
The two given waves resembled the following:
Which resulted in the following:
Can someone please shed some light on this as the teacher avoided the question when asked about it and nobody had a clue. I researched and found something about beat frequency, but we weren't even told the correct answer so I couldn't tell if you were supposed to work out the beat frequency. Thanks for any help.
Superposition of waves with different frequencies.
