Question

a standing wave is formed by waves of frequency 256hz.the speed of the wave is 128m/s.what is the distance between the nodes​

Answer 1

V = f * λ Velocity = frequency * wavelength

λ = V / f = 128 m/s / 256 / s= .5 m is the wavelength

There will be nodes at o, λ/2, λ, 3λ/2 or at intervals of λ/2

The distance between nodes is ".25 m"
