A medical ultrasound transducer emits a sound wave that propagates through muscle tissue at a speed of 1540 m/s. The wavelength of this wave is 0.22 mm.
Calculate the frequency of the wave.
State the unit of frequency.
Use the equation:
v=f×λ v = f \times \lambda v=f×λ64 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.
