One end of a taut string of length $3 \ m$ along the $x$-axis is fixed at $x=0$. The speed of the waves in the string is $100 \ m / s$. The other end of the string is vibrating in the $y$-direction so that stationary waves are set up in the string. The possible waveform$(s)$ of these stationary waves is (are)

A wave represented by the equation $y = A cos (kx - \omega t)$ is superimposed with another wave to form a statioary wave such that the point $x =0$ is a node. The equation of the other wave is:
The frequencies of two sound sources are $256 Hz$ and $260 Hz$. At $t = 0,$ the intensity of sound is maximum. Then the phase difference at the time $t = \frac{1}{16}\, sec$ will be
Stationary waves are produced in $10\,m$ long stretched string. If the string Vibrates in $5$ segments and wave velocity $20\,m/s$ the frequency is ..... $Hz$
The velocity of waves in a string fixed at both ends is $2 m/s$. The string forms standing waves with nodes $5.0 cm$ apart. The frequency of vibration of the string in $Hz$ is
The diagram below shows as instantaneous position of a string as a transverse progressive wave travels along it from left to right Which one of the following correctly shows the direction of the velocity of the points $1,2$ and $3$ on the string
A cylindrical tube $(L = 120\,cm.)$ is resonant with a tuning fork of frequency $330\,Hz$. If it is filling by water then to get resonance minimum length of water column is ..... $cm$ $(V_{air} = 330\,m/s)$
A pipe open at both ends has a fundamental frequency $f$ in air. The pipe is dipped vertically in water so that half of it is in water. The fundamental frequency of the air column is now ..... $f$
