The length of an elastic wave propagating in water is 1 cm. Determine the frequency of the vibration source if the propagation velocity of this wave is 1.5 km / s.
Given: λ = 1 cm υ = 1.5 km / s
Find: ν-?
SI: λ = 0.01 m υ = 1500 m / s
Decision:
υ = ν * λ => ν = υ / λ ν = 1500m / s / 0.01m = 150000 Hz = 150 kHz
Answer: ν = 150 kHz
