Question

A string of a sonometer of length 2 metre between the bridge vibrates in second harmonic the amplitude of vibration is maximum at

Answer 1

Hey mate !

_________

We know,

2nd Harmonic means 1st Overtone

As both edges are clamped, Both are nodes

We can take, l = lamda

lamda = 2m

So points of maximum amplitude are :- 1/2m and 3/2 m

_______

Thanks …ʘ‿ʘ

Answer 2

Answer:

At x= 0.5m , 1.5m

Sonometer works as standing wave

For standing /stationary wave, maximum Amplitude occurs at Antinodes.
