marco is conducting an experiment. he knows the wave that he is working with has a wavelength of 32.4 cm. if he measures the frequency as 3 hertz, which statement about the wave is accurate?\nthe wave has traveled 32.4 cm in 3 seconds.\nthe wave has traveled 32.4 cm in 9 seconds.\nthe wave has traveled 97.2 cm in 3 seconds.\nthe wave has traveled 97.2 cm in 1 second.
Answer
Explanation:
Step1: Recall wave - speed formula
The speed of a wave $v$ is given by the product of its frequency $f$ and wavelength $\lambda$, i.e., $v = f\lambda$.
Step2: Identify given values
We are given that $\lambda=32.4$ cm and $f = 3$ Hz.
Step3: Calculate wave - speed
Substitute the values into the formula: $v=f\lambda=3\times32.4 = 97.2$ cm/s. This means the wave travels 97.2 cm in 1 second.
Answer:
The wave has traveled 97.2 cm in 1 second.
