A geophysicist uses a seismic reflection survey to map granite bedrock. The longitudinal seismic wave (P-wave) generated has a frequency of 80 Hz80\text{ Hz}80 Hz. In granite, the speed of this seismic wave is 5000 m/s5000\text{ m/s}5000 m/s.
Calculate the wavelength of this seismic wave in granite.
Use the equation:
wavelength=wave speedfrequency \text{wavelength} = \frac{\text{wave speed}}{\text{frequency}} wavelength=frequencywave speed14 exam-style questions on AQA GCSE Physics 6.1 Waves in air, fluids and solids, covering 6.1.1 Transverse and longitudinal waves, 6.1.2 Properties of waves, 6.1.3 Reflection of waves, 6.1.4 Sound waves (HT only), and 6.1.5 Waves for detection and exploration (HT only). Each one has a worked solution and a mark scheme showing where the marks go.
