A
Higher
a (a) Frequency of $9^{t h}$ harmonic $=\frac{9}{2 L} \sqrt{\frac{T}{\mu}}=n$
frequency of $7^{t h}$ harmonic $=\frac{7}{2 L} \sqrt{\frac{T}{\mu}}=n_{1}$
clearly frequency of $9^{t h}$ harmonic,is higher than the seventh harmonic.

Two factories are sounding their sirens at $800\, Hz$ . A man goes from one factory to other at a speed of $2\,m/s$. The velocity of sound is $320\, m/s$. The number of beats heard by the person in one second will be
A tuning fork of frequency $480\, Hz$ is used in an experiment for measuring speed of sound $(\nu )$ in air by resonance tube method. Resonance is observed to occur at two successive lengths of the air column, ${\ell _1} = 30\,cm$ and ${\ell _2} = 70\,cm$. Then $\nu$ is equal to ..... $ms^{-1}$
The intensity of sound from a radio at a distance of $2$ metres from its speaker is $1 \times {10^{ - 2}}\mu \;W/{m^2}.$ The intensity at a distance of $10$ meters would be
A transverse progressive wave on a stretched string has a velocity of $10\,m{s^{ - 1}}$ and a frequency of $100 Hz.$ The phase difference between two particles of the string which are $2.5 cm$ apart will be
The sound intensity level at a point $4 \,m$ from the point source is $10 \,dB$, then the sound level at a distance $2 \,m$ from the same source will be ........ $dB$
An air column in a pipe, which is closed at one end, will be in resonance wtih a vibrating tuning fork of frequency $264\, Hz$ if the length of the column in $cm$ is (velocity of sound $= 330\, m/s$)
The linear density of a vibrating string is $1.3 \times 10^{-4}\, kg/m.$ A transverse wave is propagating on the string and is described by the equation $Y = 0.021\, \sin (x + 30t)$ where $x$ and $y$ are measured in meter and $t$ in second the tension in the string is ..... $N$
A uniform string oflength $20\ m$ is suspended from a rigid support. A short wave pulse is introduced at its lowest end. It starts moving up the string. The time taken to reach the supports is (take $g= 10 $ $ms^{-2}$ )
