An ocean wave travels 10.9 m in 5.1 s. the distance between two consecutive wave crests is 4 m. what is the frequency of the wave? answer in units of hz.
The speed of the wave is given by Distance divided by time. Speed = 10.9/5.1 = 2.14 m/s But; speed is also given by frequency multiplied by wavelength Wavelength is 4 m( distance between two successive crests) thus; 2.14 = 4 × f f = 2.14/4 = 0.535 Hz
