An ultrasound system uses a transducer to scan a patient's liver. The speed of the ultrasound wave in liver tissue is 1540 m/s.
The transducer operates at a frequency of 4.4 MHz (where 1 MHz=1,000,000 Hz1\text{ MHz} = 1,000,000\text{ Hz}1 MHz=1,000,000 Hz).
Calculate the wavelength of this ultrasound wave in metres.
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.
