Question

A sound of signal of 128 vibrations per second and the sound has a wave length of 2.7m calculate the speed of the wave

Answer 1

wavelength is 2.7 m the vibration of 128 per second hands speed is equal to wavelength into frequency speed is equal to 2.7 into 128 / 60 is equal to 1296

Answer 2

Answer:

The speed with which the wave travel is 345.6 m/s.

In this case, a sound signal of 128 vibrations per second has a wavelength of 2.7 m
