Below is everything the examiners think you know, if you're not sure of something click on the link to watch my YouTube video explanation. For a copy of these you can print off, get the FREE revision guide I wrote for you.

• I can describe using evidence that waves transfer energy not matter

• I can draw and label transverse and longitudinal waves

• I can describe the direction of movement and the direction of energy transfer for both transverse and longitudinal waves

• I can define the terms, period, wave velocity, wave front, amplitude, wavelength and frequency

• I can describe how to measure the speed of waves in air and on water

• I can recall the units needed for v = fλ

• I can rearrange v = fλ
