Homework Statement
Hi guys I have this problem that I can't solve..
Suppose to have this situation:
when M=16kg the cord vibrates in one of its normal ways of oscillation.
when M=6.25 we have the same frequency but 3 more nodes.
How many are the nodes of the stationary wave in the first and in the second case?Knowing that for the n harmonic the frequency is
[itex]\frac{n}{2L}\sqrt{\frac{T}{u}}[/itex]
3more node → n harmonic first case +2 so
[itex]\frac{n1}{2L}\sqrt{\frac{T1}{u}}[/itex]=[itex]\frac{n2}{2L}\sqrt{\frac{T2}{u}}[/itex]
but it's wrong.
How can I solve this?
Thanks in advance.
