Ok, I am working with problems dealing with Speed=(lambda) (frequency).(adsbygoogle = window.adsbygoogle || []).push({});

I have a question in determining whether Im solving these correctly. I sometimes get confused as what the wavelength is.

1. A longitudinal wave with a frequency of 25.0Hz travels along a coil spring. If the distance between successive compressions is 0.500m, what is the speed of the wave.

This is how i solved it. There is no need to show the steps becuase my question comes just when i frame the problem.

frequency=25.0hz

speed is unknown

wavelength is 0.500m

My question is would the wavelength be twice as much as the distance between successive compressions, not 0.500m.

2. Twenty five water waves pass your anchored boat in 1.0 min. If the separation between waves is 2.0m, what is the speed of the waves?

This is how I would set up the problem

N=25

t=1 min x 60 seconds = 60 seconds

v = unknown

wavelength is 2.0m

Same question as the first, would the wavelength be 2.0 m or 4.0 m. Because wouldnt the seperation between the waves just be a loop.

Thanks
