A string of length $1\, m$ and mass $5\, g$ is fixed at both ends. The tension in the string is $8.0\, N$. The string is set into vibration using an external vibrator of frequency $100\, Hz$. The separation between successive nodes on the string is close to .... $cm$
The equation of a progressive wave is $y = 0.02\,\sin \,2\pi \left[ {\frac{t}{{0.01}} - \frac{x}{{0.30}}} \right]$ Here $x$ and $y$ are in metre and $t$ is in second. The velocity of propagation of the wave is .... $ms^{-1}$
In a closed end pipe of length $105 \,\,cm,$ standing waves are set up corresponding to the third overtone. What distance from the closed end, amongst the following, is a pressure Node ..... $cm$ ?
The length of the wire shown in figure between the pulleys is $1.5\, m$ and its mass is $12.0\,g$. The frequency of vibration with which the wire vibrates in three loops forming antinode at the mid point of the wire is $(g = 9.8 \,m/s^2)$
An iron block is dropped into a deep well. Sound of splash is heard after $4.23 \,s$. If the depth of the well is $78.4 \,m$, then find the speed of sound in air is ............ $m / s$ $\left(g=9.8 \,m / s ^2\right)$
The figure represents the instantaneous picture of a longitudinal harmonic wave travelling along the negative $x$-axis. Identify the correct statement $(s)$ related to the movement of the points shown in the figure. The maximum displaced points are
The standing wave in a medium is expressed as $y=0.2 \sin (0.8 x) \cos (3000 t) \,m$. The distance between any two consecutive points of minimum or maximum displacement is
A transverse wave is represented by the equation $y = {y_0}\sin \frac{{2\pi }}{\lambda }(vt - x)$ For what value of $\lambda$, the maximum particle velocity equal to two times the wave velocity
