Question

Quizplus · Accepted Answer

The speed of sound in seawater is given by the formula:

v = fλ

where v is the speed of sound, f is the frequency, and λ is the wavelength.

Substituting the given values, we get:

v = 440 Hz x 3.5 m = 1540 m/s

Therefore, the correct choice is C.

The Musical Note a Has a Frequency of 440 Hz
