A series of free GCSE/IGCSE Physics Notes and Lessons.
The following diagram shows the formula for velocity of waves: wave velocity = frequency × wavelength.

Required Practical: Ripple Tank
How to use a ripple tank to determine the wavelength, frequency and speed of water waves?
Required Practical: Waves in a Solid
How to use a standing wave to measure the wavelength, frequency and wavespeed of waves in a solid?
Velocity = frequency × wavelength
v = f × λ
GCSE Physics Required Practical on Waves
Standing waves on a piece of elastic shock cord, moving water waves in a ripple tank.
How to count the waves and calculate wave speed from experimental data?
