Learning objectives
What the syllabus expects you to be able to do.
- 7.1.1Describe wave motion using ropes, springs and ripple tanks.
- 7.1.2Use the terms displacement, amplitude, phase difference, period, frequency, wavelength and speed.
- 7.1.3Use the time-base and y-gain of an oscilloscope to find frequency and amplitude.
- 7.1.4Derive v = fλ from the definitions.
- 7.1.5Recall and use v = fλ.
- 7.1.6Recognise that a progressive wave transfers energy.
- 7.1.7Recall and use intensity = power/area and intensity ∝ amplitude².
