-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

Very useful points thank you .Do u think sound waves are likely to come us on the core science physics paper 2016

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: https://m.youtube.com/watch?v=o1dEkygywQE

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