A tuning fork resonates with a sonometer wire of length $1 \mathrm{~m}$ stretched with a tension of $6 \mathrm{~N}$. When the tension in the wire is changed to $54 \mathrm{~N}$, the same tuning fork produces $12$ beats per second with it. The frequency of the tuning fork is $\mathrm{Hz}$.
The equation of a wave motion (with $t$ in seconds and $x$ in metres) is given by $y = 7\sin \,\left[ {7\pi t - 0.4\pi x + \frac{\pi }{3}} \right]$. The velocity of the wave will be
Two trains, one coming towards and another going away from an observer both at $4\; m/s$ produce whistle simultaneously of frequency $300 \;Hz$. Find the number of beats produced
A body sends waves $100\, mm$ long through medium $A$ and $0.25\, m$ long in medium $B$. If the velocity of waves in medium $A$ is $80\, cms^{-1}$. The velocity fo waves in medium $B$ is .... $ms^{-1}$
For a certain organ pipe three successive resonance frequencies are observed at $425 \,\,Hz$, $595\,\, Hz$ and $765\,\, Hz$ respectively. If the speed of sound in air is $340 \,\,m/s$, then the length of the pipe is .... $m$
Two similar sonometer wires given fundamental frequencies of $500Hz$. These have same tensions. By what amount the tension be increased in one wire so that the two wires produce $5$ beats/sec .... $\%$
