Quizplus · Accepted Answer

We know that speed of a wave (v) is given by the equation: v = λ f
where λ is the wavelength and f is the frequency.
Substituting the given values:
v = (25.4 cm) * (1.63 kHz) = 41.402 m/s
Rounding off to three significant figures, we get the answer as 414 m/s, which is closest to option C.
