The video below summarises wave properties. Watch it as a recap.
To help us visualise what all waves are doing, we observe wavefronts in a ripple tank and link those images to the behaviour of light, sound, radio, microwaves etc.

Now Challenge Yourself. To test the level of competence you have reached, choose one of the options from Section B (Using The Wave Equation) in the Task Menu below.
Look at the task menu and decide where you need to focus your efforts before you decide which of the question sheets below to complete.
Sound waves make the microphone vibrate and induce an electrical signal with exactly the same frequency as the sound.
The Electrical signal can be displayed on an oscilloscope.
Bigger amplitude shows a louder sound.
