In an organ pipe whose one end is at $x = 0$, the pressure is expressed by $p = {p_0}\cos \frac{{3\pi x}}{2} \,\,sin\,\, 300\pi t$ where $x$ is in meter and $t$ in $sec$. The organ pipe can be
An organ pipe $P_1$ closed at one end vibrating in its first overtone. Another pipe $P_2$ open at both ends is vibrating in its third overtone. They are in a resonance with a given tuning fork. The ratio of the length of $P_1$ to that of $P_2$ is
Two wires are fixed in a sonometer. Their tensions are in the ratio $8 : 1$. The lengths are in the ratio $36:35.$ The diameters are in the ratio $4 : 1$. Densities of the materials are in the ratio $1 : 2$. If the lower frequency in the setting is $360 Hz.$ the beat frequency when the two wires are sounded together is
Sound waves travel at $350\,\, m/s$ through a warm air and at $3500\,\, m/s$ through brass. The wavelength of a $700\,\, Hz$ acoustic wave as it enters brass from warm air
The equation of stationary wave along a stretched string is given by $y = 5\sin \frac{{\pi x}}{3}\cos 40\pi t$ where $x$ and $y$ are in centimetre and $t$ in second. The separation between two adjacent nodes is .... $cm$
Three coherent waves of equal frequencies having amplitude $10 \,\, \mu m$, $4\,\,\mu m$ and $7 \,\,\mu m$ respectively, arrive at a given point with successive phase difference of $\pi /2$. The amplitude of the resulting wave in $mm$ is given by
A wire is stretched between two rigid supports vibrates in its fundamental mode with a frequency of $50\,\, Hz$ . The mass of the wire is $30\,\, g$ and its linear density is $4\, \times \, 10^{-2}\,\, kg/m$ . The speed of the transverse wave at the string is ...... $ms^{-1}$
A source of sound placed at the open end of a resonance column sends an acoustic wave of pressure amplitude ${\rho _0}$ inside the tube. If the atmospheric pressure is ${\rho _A},$ then the ratio of maximum and minimum pressure at the closed end of the tube will be
The extension in a string, obeying Hooke's law, is $x$. The speed of sound in the stretched string is $v$. If the extension in the string is increased to $1.5x$, the speed of sound will be
