calculating the speed of a wave\nwhat is the speed of a wave that has a frequency of 125 hz and a wavelength of 1.25 meters? express your answer to the nearest whole number.\nmeters per second
Answer
Answer:
156
Explanation:
Step1: Recall wave - speed formula
$v = f\lambda$
Step2: Substitute given values
$f = 125\ Hz$, $\lambda=1.25\ m$, so $v=125\times1.25$
Step3: Calculate the result
$v = 156.25\ m/s$. Rounding to the nearest whole number gives 156 m/s.
