The speed of ultrasound waves in human soft tissue is 1540 m/s.
A medical transducer emits an ultrasound beam with a wavelength of 2.2 × 10-4 m in human tissue.
Calculate the frequency of this ultrasound beam.
State the unit.
Use the equation:
frequency=speedwavelength \text{frequency} = \frac{\text{speed}}{\text{wavelength}} frequency=wavelengthspeed64 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.
