Which statement about sound waves in air and radio waves in air is correct?
- Sound waves and radio waves are both longitudinal.
- Sound waves and radio waves are both transverse.
- Sound waves are longitudinal and radio waves are transverse.
- Sound waves are transverse and radio waves are longitudinal.
A seismic geophone records ground vibrations caused by a low-frequency shear wave travelling through the Earth's crust. The figure below shows the displacement recorded over a period of time.
Calculate the frequency of the wave shown in the trace.
Write down the equation that links wave speed, frequency, and wavelength.
The wave is travelling through the ground at a speed of 3.2 km/s.
Calculate the wavelength of this wave in metres.
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.
