Oh wow this what u look like. Legend

Excellent video. You've explained this topic in an easy to understand way (which helps because I'm reasonably sure we're doing this practical tomorrow). Thanks!

[@kieranarmstrong8200]

Cheers mate this helped a lot

[@sajdahamad9980]

Thank you.

[@eh2286]

very helpful thank you so much!!

[@JLee-xl4dt]

Thank you 🙏 😭

[@elis5955]

what if you changed the length?

[@nowthenad3286]

25% error seems rather large.

[@sajdahamad9980]

how would you investigate the effect of length and mass per unit length on the fundamental frequency?

[@elis5955]

Yes, this is also very interesting. What would happen? I can't find an experiment investigating the relationship between the length of the string and its fundamental frequency :(

[@ItsJustRosco.Huhhhhh]

What if instead of using only the mass in the graph the tension is used instead. Meaning that the new formula to get M(mue) would be M(mue)=[1/(4L^2 * gradient of graph)] or if using exact values M(mue) = [T/(4L^2*f^2)]. Would that also work?

[@isholasamuel4130]

which alternative apparatus can be used in place of the signal generator?

[@waitroseolives]

pls be my teacher.
