1. Wave Velocity

2. Velocity Waves travel through air at around 340 m/s
Waves travel through water at 4 x air
Velocity

3. V = λF F = V/ λ λ = V/F V = Distance/Time
Wave velocity = wavelength X frequency
V = λF
F = V/ λ
λ = V/F
V = Distance/Time

4. If a water wave vibrates up and down two times each second and the distance between wave crests is 1.5m, what is the frequency of the wave? What is the wavelength? What is its velocity?

5. What is the wavelength of a 340-Hz sound wave when the speed of sound in air is 340 m/s?
