The equation of a certain progressive transverse wave is y = 2 sin 2 π(t0.01−x30), where x and y are in cm and t in seconds. Calculate the period of the wave.
0.001s
0.010s
10.000s
100.000s
Correct answer is B
Compare: Y = 2 sin 2 π(t0.01−x30)
with the wave equation,
y = A sin 2 π(tT−xλ)
⇒ tT=t0.01
T = 0.010s
