An acoustic hum detected by an underwater research vessel has a frequency of 85 Hz.
The speed of this acoustic wave propagating through seawater is 1530 m/s.
Calculate the wavelength of this acoustic wave.
Use the equation:
wave speed=frequency×wavelength \text{wave speed} = \text{frequency} \times \text{wavelength} wave speed=frequency×wavelength64 exam-style questions on Edexcel GCSE Physics 4.1 Wave properties, covering 4.1.1 Waves transfer energy and information, 4.1.2 Frequency, wavelength, amplitude, period and wavefronts, 4.1.3 Longitudinal and transverse waves, 4.1.4 The wave speed equations, 4.1.5 Measuring wave velocity, and 4.1.6 Calculating depth or distance from waves.
