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
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 non-integer numbers of nodes in a wave? |
