An experiment is set up to investigate standing waves on a stretched elastic cord, as shown in the diagram below.

State a suitable laboratory instrument to measure the distance between the vibrator and the fixed clamp.
Determine the wavelength, λ\lambdaλ, of the standing wave in metres.
Calculate the wave speed, vvv, of the wave on the cord.
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.
