WavesAn open organ pipe of length $L$ vibrates in its fundamental mode. The wavelength of the sound wave produced is:
WavesA string of length $L$ fixed at both ends vibrates in its second overtone (3rd harmonic). The number of nodes in the standing wave is:
WavesA siren emitting frequency $f = 1000\,\text{Hz}$ approaches a stationary listener with speed $34\,\text{m/s}$ (speed of sound $v=340\,\text{m/s}$ ). Observed frequency is:
WavesTwo strings $(A, B)$ having linear densities $\mu_{A}=2 \times 10^{-4} \mathrm{~kg} / \mathrm{m}$ and, $\mu_{B}=4 \times 10^{-4} \mathrm{~kg} / \mathrm{m}$ and lengths $L_{A}=2.5 \mathrm{~m}$ and $L_{B}=1.5 \mathrm{~m}$ respectively are joined. Free ends of $A$ and $B$ are tied to two rigid supports $C$ and $D$ , respectively creating a tension of 500 N in the wire. Two identical pulses, sent from $C$ and $D$ ends, take time $t_{1}$ and $t_{2}$ , respectively, to reach the joint. The ratio $t_{1} / t_{2}$ is :
WavesThe equation of wave is given by $Y={10}^{-2}\sin 2\pi \left(160t-0.5x+\dfrac{\pi }{4}\right)$ , where $x$ and $Y$ are in $m$ and $t$ in $s$ . The speed of the wave is _______ $km{h}^{-1}$ .
WavesA transverse harmonic wave on a string is given by $y\left(x,t\right)=5\sin \left(6t+0.003x\right)$ where $x$ and $y$ are in $cm$ and $t$ in $\sec$ . The wave velocity is _________ $m{s}^{-1}$ .
