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.

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.

Electromagnetic Waves

This shows important data and uses of the full range of Electromagnetic Waves
Your task and the Grading Rubric for Electromagnetic Waves

Sound Waves

Your task for Sound

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.
