A wave in a string has an amplitude of 2 cm. The wave travels in the +ve direction of x axis with a speed of 128 m/s. and it is noted that 5 complete waves fit in 4m length of the string. The equation describing the wave is
- Ay = (0.02) m sin (15.7 x 2010t)
- By = (0.02) m sin (15.7 x + 2010t)
- Cy = (0.02) m sin (7.85 x 1005t)
- Dy = (0.02) m sin (7.85 x + 1005t)
