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

[tex]v = \lambda f[/tex]

so we will have

[tex]\lambda = 32.4 cm[/tex]

[tex]\lambda = 0.324 m[/tex]

frequency of the wave is given as

[tex]f = 3 Hertz[/tex]

now we know that

[tex]v = \lambda f[/tex]

[tex]v = 0.324 \times 3[/tex]

[tex]v = 0.972 m/s[/tex]

so wave will travel 97.2 cm in 1 s
