How is sound produced? Key words: Transverse, Longtitudinal, particles
How are standing waves set up in the instruments? Key words: incident, reflected, interference, wavelength, string/pipe length
What factors determine the sound? Key words: frequency, string/pipe length, harmonics, timbre, tension of string, temperature of air
Do the instruments sound different when they play the same note? Needs to be fully explained and link to physics ideas
Do strings and pipes of the same length produce the same fundamental frequency? Again needs to be fully explained with linking to physics ideas.
