Standing Waves Introduction

Looking for AP Physics 1 study guides, multiple choice problems, free response question solutions and a practice exam? www.ultimatereviewpacket.com/...
Reflection with and without inversion caused by fixed and free ends are demonstrated. Standing wave patterns at 5 different frequencies are demonstrated. A standing wave animation is shown to understand to how standing wave patterns are created. Nodes and antinodes are defined and demonstrated. Want Lecture Notes? www.flippingphysics.com/stand... This is an AP Physics 1 Topic.
Based on a suggestion from Dan Russell, I redid the "reflection with and without inversion" part. This is much better. Thanks Dan!
0:00 Reflection with inversion due to a fixed end
0:29 Reflection without inversion due to a free end
1:00 The demonstration at 15 Hz
1:37 Why the Liquid Crystal Display (LCD) is flashing
2:16 The demonstration at 30 Hz
3:21 The 15, 30, and 45 Hz demonstrations all together
4:12 “Plucking” the string to visualize the wave pulses
4:40 The standing wave animation
7:39 Defining nodes and antinodes using the animation
8:15 Identifying nodes and antinodes in the demonstrations
9:36 Standing wave patterns only work at certain wavelengths

    I can't seem to find an answer anywhere to a question I have; maybe you can help. In the case of a plucked string (not a string induced to vibrate by an oscillator) will the wave move in a single plane according to the direction it was plucked, for example, up and down, but not side to side, OR, will the wave begin to drift off of this up and down axis and begin to move more like a skipping rope? Or perhaps remain moving in a flat plane, but not strictly up and down, but at varying angles side to side as well?

    Does the amplitude decrease with the increase in the nodes?
