Vedclass · Answer

(B) The sound source and its reflection from the wall create a stationary wave pattern due to interference.Given frequency $f = 170 \, Hz$ and speed of sound $v = 340 \, m/s$.The wavelength $\lambda$ is given by $\lambda = \frac{v}{f} = \frac{340}{170} = 2 \, m$.Positions of minimum intensity (nodes) in a stationary wave are separated by a distance of $\frac{\lambda}{2}$.Therefore,the distance between two adjacent positions of minimum intensity is $\frac{\lambda}{2} = \frac{2}{2} = 1 \, m$.

$A$ stationary wave is formed having $4$ nodes along the $120 \,cm$ length of the string. The wavelength of the wave is (in $\,cm$)

$A$ wave is represented by the equation $y = 10 \sin 2\pi(100t - 0.02x) + 10 \sin 2\pi(100t + 0.02x)$. The maximum amplitude and loop length are respectively:

The equation of a stationary wave is $ y = 2 \sin \left( \frac{\pi x}{15} \right) \cos (48 \pi t) $. The distance between a node and its next antinode is (in $units$)

$A$ stretched string is fixed at both ends. It is made to vibrate so that the total number of nodes formed in it is '$x$'. The length of the string in terms of the wavelength of waves formed in it is $(\lambda = \text{wavelength})$
