Formula used: Fundamental frequency of a sonometer $f=\dfrac{1}{2l}\sqrt{dfrac{T}{mu}}$.
Sonometer zaus yog dab tsi?
Ntau zaus ntawm ib lub sonometer yog muab los ntawm. f=2l1mMg, qhov twg l yog qhov ntev ib m yog qhov hnyav rau ib chav tsev ntev ntawm txoj hlua. Zaus ntawm tus sonometer thaum qhov loj yog raus hauv dej. fw=2l1mMg-Vρwg. Ntawm no Vρg yog lub zog buoyancy.
Dab tsi yog qhov zaus ntawm Sonometer hlau?

Dab tsi yog qhov tseem ceeb ntawm Sonometer?
Qhov tseem ceeb ntawm tus sonometer hlau ntawm qhov ntev l yog fo. Ib tug choj tam sim no qhia ntawm qhov deb ntawm Δl los ntawm qhov chaw ntawm cov hlau (Δ<<l). Tus naj npawb ntawm cov neeg ntaus tau hnov txog ib ob yog tias ob sab ntawm tus choj tau teeb tsa kom vibrate hauv lawv qhov tseem ceeb yog.
Yuav ua li cas yog tus qauv rau qhov tseem ceeb zaus?
waves. Qhov yooj yim zaus (n=1) yog ν=v/2l.
