A sound wave of frequency 245 Hz travels with the speed of 300 ms-1 along the positive x-axis. Each point of the wave moves to and fro through a total distance of 6 cm. What will be the mathematical expression of this travelling wave?
1
Y(x, t) = 0.03 [sin 5.1x - (0.2 × 103)t]
2
Y(x, t) = 0.03 [sin 5.1x - (1.5 × 103)t]
3
Y(x, t) = 0.06 [sin 5.1x - (1.5 × 103)t]
4
Y(x, t) = 0.06 [sin 0.8x - (0.5 × 103)t]
