The waves are observed where the two waves are upwardly displaced.]]> 2017-03-30 23:04:24 UTC https://padlet.com/isabpard/5va6k7tdriaz/wish/163846356 isabpard https://padlet.com/isabpard/5va6k7tdriaz/wish/163846886 2017-03-30 23:11:18 UTC https://padlet.com/isabpard/5va6k7tdriaz/wish/163846886 Destructive Interference isabpard https://padlet.com/isabpard/5va6k7tdriaz/wish/163846994 Occurs along the medium where interfering waves have an opposite displacement. The waves have the same maximum displacement but are travelling in opposite directions. There is no resulting displacement of the particles in the medium. The upward pulse of one of the waves is canceled out by the downward pull of the other.]]> 2017-03-30 23:12:29 UTC https://padlet.com/isabpard/5va6k7tdriaz/wish/163846994 isabpard https://padlet.com/isabpard/5va6k7tdriaz/wish/163847538 2017-03-30 23:18:40 UTC https://padlet.com/isabpard/5va6k7tdriaz/wish/163847538 isabpard https://padlet.com/isabpard/5va6k7tdriaz/wish/163847670 They do not need to have equal amplitudes for destructive interference to occur. Since they have differing displacements there is no total cancellation. ]]> 2017-03-30 23:20:29 UTC https://padlet.com/isabpard/5va6k7tdriaz/wish/163847670 Real life applications? isabpard https://padlet.com/isabpard/5va6k7tdriaz/wish/163848034 When music is played in an auditorium, the sound waves bounce of the walls. As the waves interfere constructively, the acoustics in the auditorium become exceptional. If the waves interfere destructively, then the sound will not be heard clearly.]]> 2017-03-30 23:24:37 UTC https://padlet.com/isabpard/5va6k7tdriaz/wish/163848034 isabpard https://padlet.com/isabpard/5va6k7tdriaz/wish/163848265 An automobile muffler is another example. The exhaust system in a car makes a lot of noise, and without a car muffler, the noise would be very disruptive. The muffler produces a sound wave out that collides with the waves of the exhaust system, cancelling out the noise. ]]> 2017-03-30 23:27:27 UTC https://padlet.com/isabpard/5va6k7tdriaz/wish/163848265 Citations isabpard https://padlet.com/isabpard/5va6k7tdriaz/wish/163848558
