Question

wave of frequency is 256 Hertz is propagating at a speed of 330m/s. what will be the speed of wave having frequency of 512 hz in the same medium?

Answer 1

Answer: 660 m/s

Explanation:.

velocity =

frequency X wavelength

Hence,

V = 256 * wavelength

330 = 256 * wavelength

Wavelength = 330/256

Now, V' = n' * wavelength

V' = 512 * 330/256

V' = 2*330

V' = 660 m/s
