Finding Wavelength: Ripple Tank Wave Speed & Frequency

[x-little-reme]

Hey, I'm stuck on how to find the wavelength of a question I have got given for homework.



The question shows a tray of water with waves and the length of the tray is 10cm. It says... The diagram shows some waves in a ripple tank traveling at a sppeed of 6cm/s. What is a) the wavelength b) the frequency



Can anyone help?? xx

How many waves are show in the picture

It doesn't really show it that clearly. x

count the number of "hills" and "valleys", one wavelength is one "hilL" + one "valley".

Then divide by the length of the tray.
