Standing Waves Flashcards
1
Q
How are standing waves created?
A
Pulses, which moves a string perpendicular to the d of motion
Which occur when 2 waves interfere from opposite directions
2
Q
What do the waves look like in standing waves
A
The wave reflects from the point and then have an inverted amplitude
3
Q
Why is it called standing waves?
A
There are some points that look like they are standing still
4
Q
What is a node?
A
Points of no displacement (amplitude)
The standing still part
5
Q
Why do nodes look like they’re not moving?
A
Due to the destructive interference between both waves
6
Q
What is an antinode?
A
Points of max displacement (amplitude)
7
Q
Why do antinodes move?
A
Due to the constructive intereference between both waves
