3B.1 Wave Phase And SuperPosition Flashcards
what is a phase
the stage a given point on a wave is through a complete cycle
a complete cycle is equivalent to?
360 or 2pi
phase table
page 102
what are wavefronts line
they are connecting points on the wave with exactly the same phase
what happens when waves meet
each wave will try to cause a wave displacement according to its wave at that position
what is superposition
it represents the overall vector sum of the waves that meet in a single point individual displaced at each point the waves meet
what happens after superposition
each wave would move past each other as the energy continues traveling in its original direction
what happens when two waves are traveling on water
when a wave is traveling on the surface of the water they would try to displace the water upwards briefly so when two waves meet them would both displace the water briefly forming a superposition
what is constructive interference
the superposition effect of two waves in phase, producing a larger amplitude resultant wave
destructive interference
the superposition effect of two waves that are out of the wave, producing a smaller amplitude resultant wave
