[SOLVED] Wave Behaviour Question

1. The problem statement, all variables and given/known data
This is probably going to have a very simple answer, but its a simple answer I don't know. It has to do with figuring out the velocity and wavelength of a wave between 2 nodes. Heres the question.

The distance between two successive nodes in a vibrating string is 10 cm. The frequency of the source is 30 Hz. What is the wavelength of the waves? What is their velocity?

2. Relevant equations

3. The attempt at a solution
I thought maybe the wavelength would be half of the distance between the nodes but I don't think thats true.

What makes you think it is not true? Can you draw a diagram to yourself?

Well when I used the same theory in another question, the numbers didn't seem right but I will go back and try again.

Perhaps in the second case you made an arithmetical mistake.

It would appear that was the case :)

I think I've got it, thanks
