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?


a.The wave has traveled 32.4 cm in 3 seconds.

b.The wave has traveled 32.4 cm in 9 seconds.

c.The wave has traveled 97.2 cm in 3 seconds.

d.The wave has traveled 97.2 cm in 1 second.

Recall that to compute for the wave's speed, v, we have

v = λf

where λ is the wavelength of wave and f is wave's frequency.

Plugging our information into this equation, we have

v = (32.4 cm)(3 Hz) = 97.2 cm/s

Thus, the statement that best describes this is D.

Answer:

d.The wave has traveled 97.2 cm in 1 second.

Explanation:

As we know that the speed of the wave is given as

\(v = \lambda f\)

so we will have

\(\lambda = 32.4 cm\)

\(\lambda = 0.324 m\)

frequency of the wave is given as

\(f = 3 Hertz\)

now we know that

\(v = \lambda f\)

\(v = 0.324 \times 3\)

\(v = 0.972 m/s\)

so wave will travel 97.2 cm in 1 s
