Question

what happen to no. of loops on string in ac vibrator exp. when we increase weight in the pan?

Answer 1

Answer:

Melde's experiment is ideal to study the behavior of standing waves. Students can even visually determine wavelength, period and amplitude of waves. A string undergoing transverse vibration illustrates many features common to all vibrating acoustic systems just like the vibrations of a violin or guitar string.

Answer 2

No of loops per second = frequency

$\nu = \frac{1}{2l} \sqrt{\frac{T}{\mu} }$

where, l = length, T = tension, μ = linear mass density

ν ∝ √Τ

When weight is increased, Tension increases and hence frequency increases.

No of loops increases.
