An infrasound sensor records the atmospheric pressure variations caused by a volcanic eruption. The wave trace recorded by the sensor is shown below:
Calculate the frequency of the infrasound wave.
State the equation that links frequency, wavelength, and wave speed.
The infrasound wave is travelling through the atmosphere at a speed of 340 m/s340\text{ m/s}340 m/s. Calculate the wavelength of this wave.
Waves in air, fluids and solids Questions
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.
