Term
What is superpositioning of waves? 

Definition
When 2 waves collide, they can constructively or destructively interfere (merge). 


Term
When 2 waves superposition and pass through each other, what happens to them? IE, are they preserved in their original forms, and if not, what do they look like? 

Definition
The waves after superpositioning return to their "original" forms. They essentially pass through each other unchanged (sans the new wave created by superpositioning). 


Term
When you double the amplitude of a wave, do the peaks, the troughs, or both, double? 

Definition
Both! Keep this in mind while drawing. 


Term

Definition


Term
How do you calculate wave velocity in a stretched string? 

Definition
Square root of tension divided by mu (mass/length). 


Term
What is one generally important assumption that must be made/has to be present for one to do very easy/basic superpositioning two waves (has to do with frequency/wavelength)? 

Definition
The frequency/wavelength of the superpositioned waves must be the same for very easy superpositioning. 


Term
Formula for total amplitude of the superpositioning of two waves, with amplitudes a and b 

Definition


Term
Separation between nodes (or antinodes) formula 

Definition


Term
To calculate where nodes are, set amplitude to what value and solve? 

Definition
Set amplitude to 0 (that's where nodes are) 


Term
Velocity's relationship to wavelength and frequency 

Definition


Term
For a STANDING WAVE ON A STRING, what is the formula for wavelength (using L and m) 

Definition


Term
What does m stand for and what does it mean? 

Definition
M stands for "mode" and seems to be the wave's "structure" (allowed forms). 


Term
What is the difference between mode and node? 

Definition
Mode is the overall shape/form, nodes are where the amplitude of the wave(s) is 0. 


Term
In a fixed box, can you have noninteger numbers of nodes in a wave?
