Standing waves are produced in a string by sources at each end with a frequency of 10.0 Hx. The distance between the third node and the sixth node is 54 cm. a) What is the wavelength of the interfering waves? b) What is their speed?

Question

anonymous · Answer

I'm confused whether to double my distances and the formula to use.. o.o

anonymous · Answer

I know I have to find the velocity which would be delta distance / delta time but then I'd have to find t= velocity x delta distance. Also ahhh, I'm so confused.

Also I drew a diagram to help me but.. it's not going well so far:

The dots are the nodes, I believe.

anonymous · Answer

the distance between one node and the next= wavelength/2
the distance between the third node and the sixth node would be = 3 (wavelength/2) which equals the 54 cm.

anonymous · Answer

1) it's a half because it's not a complete wavelength - trough and crest?
2) how?
