the equation of a certain progressive transverse wave is y = 2 sin 2 \(\pi ( \frac{1}{0.01} - \frac{x}{30})\), where x and y are in cm and t in seconds. Calculate the period of the wave
A
0.001s
B
0.010s
C
10.000s
D
100.000s
correct option: b
Compare: Y = 2 sin 2 \(\pi (\frac{1}{0.01} - \frac{x}{30})\)
y = 2 sin 2 \(\pi (\frac{1}{T} - \frac{x}{\pi}\))
\(\frac{t}{T} = \frac{t}{0.01}\)
T = 0.010s
y = 2 sin 2 \(\pi (\frac{1}{T} - \frac{x}{\pi}\))
\(\frac{t}{T} = \frac{t}{0.01}\)
T = 0.010s
