Calculating Velocity and Wavelength of Waves between Nodes | Solved Question

[H^w]

[SOLVED] Wave Behaviour Question

Homework Statement

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?

Homework Equations

The Attempt at a Solution

I thought maybe the wavelength would be half of the distance between the nodes but I don't think that's true.

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

 

[H^w]

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.

 

[H^w]

It would appear that was the case :)

I think I've got it, thanks
