A transverse wave is travelling along a stretched string from right to left. The figure shown represents the shape of the string at a given instant. At this instant
the particles at $A, B$ and $H$ have downward velocity
the particles at $D, E$ and $F$ have downward velocity
the particles at $C, E$ and $G$ have zero velocity
the particles at $A$ and $F$ have maximum velocity
A wave on a string is travelling and the displacement of particles on it is given by $x = A\, sin\, (2t -0.1\, x)$. Then the wavelength of the wave is
The equation of a wave on a string oflinear mass density $0.04$ $kgm^{-1}$ is given by
$y = 0.02sin\left[ {2\pi \left( {\frac{t}{{0.04\left( s \right)}} - \frac{x}{{0.50\left( m \right)}}} \right)} \right]m$ The tension in the string is .... $N$
A string fixed at both the ends is vibrating in two segments. The wavelength of the corresponding wave is
A tuning fork of frequency $340\, Hz$ is sounded above an organ pipe of length $120\, cm$. Water is now slowly poured in it. The minimum height of water column required for resonance is .... $cm$ (speed of sound in air $= 340 \,m/s$)
A second harmonic has to be generated in a string of length $l$ stretched between two rigid supports. The point where the string has to be plucked and touched are
