This is what you need to know (from the spec)

-they are longitudinal
-cause vibrations in a medium which are detected as sound
-echoes are reflected sound waves
-pitch is determined by frequency
-volume is determined by amplitude

I'd say they may come up in context, make sure you know these key facs that are mentioned in the specification and you will be fine .

They may or may not come up. But it's best to revise everything you need to know just in case. If you're interested in P1 predictions check this video out:

Hope she is right about co2 and renewable energy source but wrong about waves and sound waves
