how does an electric guitar work?

[RandomGuy3000]

hi there,

im new to this website and this is my first thread, dont know what to expect but i have high hopes. so here goes.

i am doing some research on how electric guitars work, i have some basic ideas of how the vibration of the string is converted into electricity via the pickup.

but im still not sure.

here are the things i need help with

1. how do standing waves relate to guitars?

2. how is the frequency of the note affected by the properties of the string?

3. how does the pick-up work?

4. how do we adjust the output volume of the guitar?

any help is appreciated, thank you.

i hope this is the right section
