Question

Will Medal, and fan! Would appreciate some help thank you!


Using the wave image, what is the frequency? (Show how to set up the equation)

Answer 1

Here is the picture to my ?

Answer 2

Hello,
A fundamental equation for waves is \[v = f \lambda\] where \[\lambda\] stands for the wavelength, f is the frequency and v is the speed of the wave.
The wavelength is, according to the image, 3 meters, whereas the speed is 423m/s. Putting it all together: \[423 m/s = f*3m\]
\[f = \frac{ 423m/s }{ 3m\ } = 141Hz\]
So the frequency is 141Hz, or 141 cycles per second
