Answer:

.348 meters

Step-by-step explanation:

Speed = wavelength * frequency

340 = wl * 977

340 /977 = wavelength = .348 m

Answer:

The wavelength is =2.87m.

Step-by-step explanation:

The speed of sound, the frequency and the wavelength is related by the equation

v=fλ

speed of sound is v=340ms

frequency is f=977Hz

wavelength is λ= v/f = 977/340 =2.87m
