A student uses a signal generator connected to a loudspeaker to produce sound waves in air.
The student adjusted the setting of the signal generator so that the speaker cone vibrated more times each second.
What happened to the period of the sound waves produced?
Describe how the frequency of these sound waves can be measured experimentally using a microphone and an oscilloscope.
In a second experiment, the student measured the period of the sound waves as 0.0025 s0.0025\text{ s}0.0025 s.
Calculate the frequency of these sound waves.
Use the equation:
frequency=1period \text{frequency} = \frac{1}{\text{period}} frequency=period1Identify the correct unit for the frequency 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.
