The equation of a stationary wave is $y = 0.8\cos \,\left( {\frac{{\pi x}}{{20}}} \right)\sin 200\,\pi t$, where $x$ is in $cm$ and $t$ is in sec. The separation between consecutive nodes will be..... $cm$
The frequency of a tuning fork is $256\, Hz$. The velocity of sound in air is $344\, ms^{-1}$. The distance travelled (in $meters$) by the sound during the time in which the tunning fork complete $32$ vibrations is
$Assertion :$ The fundemental frequency of an open organ pipe increases as the temperature is increased.
$Reason :$ As the temperature increses, the velocity of sound increases more rapidly than length of the pipe.
A string wave equation is given $y=0.002 \sin (300 t-15 x)$ and mass density is $\mu=\frac{0.1\, kg }{m}$. Then find the tension in the string, (in $N$)
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 .... $\%$
A block of mass $1\,\, kg$ is hanging vertically from a string of length $1\,\, m$ and mass /length $= 0.001\,\, Kg/m$. A small pulse is generated at its lower end. The pulse reaches the top end in approximately .... $\sec$
An engine is moving with uniform speed along a circular track emitting a sound of frequency $400\, Hz$ as shown in the figure. Speed of engine is $30\, m/sec$ and speed of sound is $330\, m/sec$. An observer is standing inside the track. Maximum frequency observed by the observer is
A whistle producing sound waves of frequencies $9500\ Hz$ and above is approaching a stationary person with speed $v\ ms^{-1}$. The velocity of sound in air is $300\ ms^{-1}$. If the person can hear frequencies upto a maximum of $10,000\ Hz$, the maximum value of $v$ upto which he can hear whistle is ... $ms^{-1}$
