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 speed
Practise AQA GCSE Physics Waves in air, fluids and solids with exam-style questions for Foundation and Higher tier. 45 questions covering Transverse and longitudinal waves, Properties of waves, Reflection of waves (physics only), Sound waves (physics only) (HT only), and Waves for detection and exploration (physics only) (HT only), matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
