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 :
