JEE Main 2021 Physics question

A sound wave of frequency 245 Hz travels with the speed of 300 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 ?

• (A)Y(x,t) = 0.03 [sin 5.1 x – t]
• (B)Y(x,t) = 0.06 [sin 5.1 x – t]
• (C)Y(x,t) = 0.06 [sin 0.8 x – t]
• (D)Y(x,t) = 0.03 [sin 5.1 x – t]Correct
