sound waves. Flashcards
1
Q
why is sound a transferred?
A
as areas of alternating high pressure/ high density (compression) and low pressure/ low density (rarefaction.)
2
Q
transverse waves in liquids: why don’t these particles move?
A
very weak forces between them.
3
Q
what can’t mechanical transverse waves do?
A
can’t propagate (move) through a liquid.
4
Q
transverse waves in solids: what allows for particles in a solid to transfer energy? where is this energy transferred?
A
strong bonds between particles.
neighbouring particles.
