Topic 1 - stationary waves Flashcards
1
Q
stationary waves
A
when 2 identical waves travel in opposite directions, cross each other, they interfere with each other to produce wave shape that stands still .
2
Q
what can a stationary wave result from
A
interference between 2 identical waves travelling
wave interfering with its reflection
3
Q
nodes
A
an area on the wave where the amplitude of the 2 waves cancel out and a continuous resting point if formed
4
Q
antinode
A
this is the point on the wave where the amplitude of the 2 waves add up to create a larger resultant wave
5
Q
if the frequency increases
A
the more nodes and antinodes appear
6
Q
application of station waves
A
radio and tv antennas
microwaves ovens
