Question
A ripple tank wave has a frequency of 4 kHz and a wavelength of 5 cm. Calculate the wave speed and show the unit conversions.
Answer
200 m/s. Formula: v = f x wavelength. Substitution: v = 4000 Hz x 0.05 m. Calculation: v = 200. Final answer: 200 m/s.
Explanation
The wave speed is 200 m/s because frequency is multiplied by wavelength after converting 4 kHz to 4000 Hz and 5 cm to 0.05 m. The worked solution keeps wave speed in m/s, wavelength in metres and frequency in hertz, so it uses Science Calculation Engine v9 wave-speed reasoning correctly.
