The equation of a certain progressive transverse wave is y = 2sin2π(t/0.01 − x/30), where x and y are in cm and t in seconds. Calculate the period of the wave.
- A. 0.001 s
- B. 0.010 sCorrect
- C. 10.000 s
- D. 100.000 s
Explanation
Comparing with the standard form y = Asin2π(t/T − x/λ), the period T = 0.01s.
