Waves

Question

Waves

anonymous · Answer

$$v = \sqrt{\frac{ T }{ m/L }}$$ speed of wave on a string

parthkohli · Answer

OK I know this... could you explain the ones that involve the bulk modulus or something like that

parthkohli · Answer

$$\sqrt{\frac{Y}{\rho}}$$what is this

anonymous · Answer

Oh like stress, strain kind of stuff?

anonymous · Answer

Never really did that

parthkohli · Answer

it's there in your book

anonymous · Answer

WHICH ONE

parthkohli · Answer

freedman young

imqwerty · Answer

you want the derivation of that formula?

parthkohli · Answer

imqwerty let me search for HCV

parthkohli · Answer

yeah sure

nincompoop · Answer

are we talking about sound waves here?

parthkohli · Answer

yes, I actually want to talk about mechanical waves but I guess we're talking about sound now

nincompoop · Answer

you're talking about bulk modulus which relates to what batman said "stress" but I like to use stiffness

nincompoop · Answer

and the only way I can make a connection with bulk modulus and waves is the propagation of sound waves through objects

anonymous · Answer

I don't know how to relate what you said to waves, is Y Young's modulus or what is that formula suppose to be

nincompoop · Answer

ya I am ignoring whatever formula he typed

nincompoop · Answer

v = sqrt (bulk modulus / density )

anonymous · Answer

ok

imqwerty · Answer

okay

now to wave's origin is O
and when it will oscillate and propagate along the rod some force $F$must be produced at evry point..which will produce some stress and starin
