A student uses a ripple tank with a vibrating paddle to generate water waves.
The student adjusted the setting of the power supply to the motor so that the paddle hit the water fewer times each second.
What happened to the frequency of the waves produced?
Describe how the frequency of the water waves in the ripple tank can be measured experimentally.
In a second experiment, the student measured the frequency of the water waves as 8 Hz8\text{ Hz}8 Hz.
Calculate the period of these water waves.
Use the equation:
period=1frequency \text{period} = \frac{1}{\text{frequency}} period=frequency1Identify the correct unit for the period from the following options:
14 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.
