The period of a wave is 0.02 seconds. Calculate its wavelength if its speed is 330 ms\(^{-1}\)
A
3.3 m
B
4.0 m
C
6.6 m
D
5.0 m
Verified Correct Answer: C.
Physical Principles & Numerical Solution
T = 0.02 s; \lambda = ?; v = 330 ms⁻¹;
f = \(\frac{1}{\text{T}}\) = \(\frac{1}{0.02}\) = 50 Hz
But; v = f\lambda
\lambda = \(\frac{\text{v}}{\text{f}}\) = \(\frac{330}{50}\) = 6.6 m
