How Do You Calculate Wavelength and Wave Speed?

[Sonny18n]

Again, your equation is wavelength = speed / frequency. ( if you are unsure do a unit check... Does metres = [m/s]/(1/s) ? Yes. So you should just have 790/31200. Don't forget to look at the units to be sure... Or look at the equation. :)

Okay, so is 2.53 cm an acceptable answer?

Uh, I need help this oscillation question?

Water waves in a shallow dish are 6.0 cm long. At one point the water oscillates up and down at a rate of 4.8 oscillations per second.
a. What is the speed of the water waves?
b. What is the period of the water waves?

Oscillations? 6.0 cm is the wavelength probably.
