(b) Distance between six successive node
$ = \frac{{5\lambda }}{2} = 85cm$ ==>$\lambda = \frac{{2 \times 85}}{5} = 34\,cm = 0.34\,m$
Therefore speed of sound in gas
$ = n\lambda = 1000 \times 0.34 = 340\,m/s$

A uniform string resonates with a tuning fork, at a maximum tension of $32 \,N$. If it is divided into two segments by placing a wedge at a distance one-fourth of length from one end, then to resonance with same frequency the maximum value of tension for string will be ........... $N$
A transverse harmonic wave on a string is described by $y = 3 \sin \,(36t + 0.018x + \frac{\pi}{4})$ where $x$ and $y$ are in $cm$ and $t$ in $s$. The least distance between two sucessive crests in the wave is .... $m$
Consider two sound sources $S_1$ and $s_2$ having same frequency $100\,\,Hz$ and the observer $O$ located between them as shown in the fig. All the three are moving with same velocity in same direction. The beat frequency of the observer is .... $Hz$
A wave motion has the function $y = {a_0}\sin (\omega \,t - kx)$. The graph in figure shows how the displacement $y$ at a fixed point varies with time $t$. Which one of the labelled points shows a displacement equal to that at the position $x = \frac{\pi }{{2k}}$ at time $t = 0$
The equation of a wave disturbance is given as : $y = 0.02 cos \left( {\frac{\pi }{2} + 50\pi t} \right) cos (10 x),$ where $x$ and $y$ are in meters and $t$ in seconds. Choose the wrong statement:
A wave travelling in positive $x-$direction with $A = 0.2\;m$ has a velocity of $360 \;m/sec.$ if $\lambda = 60\;m,$ then correct expression for the wave is
A standing wave exists in a string of length $150\ cm$ , which is fixed at both ends with rigid supports . The displacement amplitude of a point at a distance of $10\ cm$ from one of the ends is $5\sqrt 3\ mm$ . The nearest distance between the two points, within the same loop and havin displacment amplitude equal to $5\sqrt 3\ mm$ is $10\ cm$ . Find the maximum displacement amplitude of the particles in the string .... $mm$
