A 340-hertz sound wave travels at 340 m/s in air with a wavelength of
A)1 m.
B)10 m.
C)100 m.
D)1000 m.
E)none of the above

Question

Quizplus · Accepted Answer

The speed of sound in air is 340 m/s and the frequency of the wave is 340 Hz. We can use the formula v = λf, where v is the speed of sound, λ is the wavelength, and f is the frequency, to find the wavelength.

λ = v/f = 340/340 = 1 meter

Therefore, the wavelength of the sound wave is 1 meter, which corresponds to choice A).
