standing waves Flashcards
1
Q
what is it called when you add two waves together by adding their amplitudes at all points?
A
superposition
2
Q
explain standing/stationary waves
A
when you have two waves of the same frequency of similar amplitude travelling in opposite directions they superpose to create standing/stationary waves
3
Q
what are nodes?
A
points where a wave cross the x-axis
4
Q
what are antinodes
A
points of amplitude, max height above the x-axis
5
Q
what is the formula for the nth harmonic
A
l = nlambda/2
