The distance between two points in phase on a progressive wave is 5cm. If the sped of the wave is 0.2ms-1, calculate its period
A
4.00s
B
2.50s
C
0.25s
D
0.04s
Verified Correct Answer: C.
Physical Principles & Numerical Solution
F = \(\frac{v}{\lambda} = \frac{0.2}{5 \times 10^{-2}} = 4Hz\)
T = \(\frac{1}{f} = \frac{1}{4} = 0.25s\)
