Question

Sound waves are refracted when there are temperature differences in the air.

True
False

Last one for the test shane :D

Answer 1

Pretty sure it's false...but let me make sure. One sec.

Answer 2

i think its false too to be honest.

Answer 3

True. Boundaries between layers of different temperature refract the waves because the layers have a different density and therefore propagate the wave at a different speed.

:/

Answer 4

wutchu think?

Answer 5

Yep...true. My intuition was wrong on that one :P

Answer 6

hah ill brb

Answer 11

this is the account and thanks kryten

Answer 12

I think when I read it I thought I thought reflection...refraction makes more sense when the sound travels through a medium of varying temperatures.

Answer 13

sound does not undergo refraction rather light does. sound is a mechanical wave specifically longitudinal wave hence no question of refraction
