Question

A sound signal of 128 vibration per second has a wave length of 2.7 m calculate the speed with which the waves travels

Answer 1

Here's your answer mate

Answer 2

Given :

wavelength = 2.7 m

frequency = 128  H z

Frequency is the number of vibrations per second .

We know that :-

speed = frequency × wavelength

==> Speed of the sound signal = 128 Hz × 2.7 m

==> Speed = 345.6 Hz m

The speed of the signal was 345.6 m/s

Hope it helps !
