16.3 The Speed of a Wave on a String

This video covers Section 16.3 of Cutnell & Johnson Physics 10e, by David Young and Shane Stadler, published by John Wiley and Sons. The lecture is part of the course General Physics - Life Sciences I and II, taught by Dr. Boyd F. Edwards at Utah State University. This video was produced through the support of the USU Physics Department and the USU Media Productions team.

So, Tension force= F=mv²/L ...{1}
where: m=string mass, L=string length, v=fλ.
Can also say that m/L=M/λ, for some mass M and wavelength λ.
So, Tension force= F=Mv²/λ=Mf²λ=(Mf)v ..{2}
I wonder if this M is really a change in mass through a time interval, which would make the rhs of {2} a "thrust" equation of sorts.
Interesting that {1} is so similar to F=mv²/R for centripetal force, R=circle radius.
Makes me think of the relationship between sinusoidal trig functions (cos,sin) and the equation for a circle: R²=x²+y².

Bro, for us in india they use the centripetal force to prove the equation with weird approximations
