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. Each one has a worked solution and a mark scheme showing where the marks go.
