The distance between the center of a condensation and the center of an adjacent
rarefaction is 70.10 cm. if the frequency is 307.0 hz, how fast are these waves moving?

 v = 215.207 m/s

Explanation:

given,

distance between center of condensation and the center of adjacent refraction (λ) = 70.10 cm = 0.7010 m  (∵ 1 cm = 0.01 m))

frequency  = 307.0 Hz

to calculate how fast the wave is moving

      V = ν λ

      v = 307.0 × 0.7010

     v = 215.207 m/s

hence, the wave is moving with velocity of  v = 215.207 m/s

not completely sure but i think it’s many moons, smaller in size and a ring system.
