Table gives the frequency and the wavelength of four waves, A, B, C and D.
Table: The frequency and the wavelength of four waves travelling in different materials
| Wave | Frequency in Hz | Wavelength in m |
|---|---|---|
| A | 200 | 1.70 |
| B | 400 | 0.85 |
| C | 500 | 3.00 |
| D | 250 | 1.36 |
Calculate the speed of wave C.
Waves A, B and D are all travelling through air. Use Table to give two conclusions about waves travelling through air.
Which wave has the longest period? Give a reason for your answer.
40 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).
