Multiple Choice

Figure 14.1 ​
The figure shows a wave.
-The wave from Fig. 14.1 is moving at a speed of 5 cm/s. If L₁ = 6 cm and L₂ = 5 cm, which wave equation describes the wave?

• A)y(x, t) = (6 cm)sin[(6.28 s^-1)t - (1.05 cm^-1)x)]
• B)y(x, t) = (3 cm)sin[(12.6 s^-1)t - (0.63 cm^-1)x)]
• C)y(x, t) = (3 cm)sin[(6.28 s^-1)t - (1.05 cm^-1)x)]
• D)y(x, t) = (6 cm)sin[(3.76 s^-1)t - (2.09 cm^-1)x)]
